Actually, they may just be here, but invisible on Friday. Well see how the week goes, but your questions were more then good enough to get a conversation going 
Speaking of questions I still haven't answered:
Damon
1. What do you think Stefan will do about Damon losing it like that?
I think we already saw what his reaction will be. He knows what happened, and he still wants to believe in the best of his brother.
2. Do you think Damon will try to apologize?
Lol, Damon doesn't apologise. I do think, however, that he'll do something to make it to to Jeremy, Elena, and the viewers.
3. Will he care?
Yes, he will. Obviously there's nothing that can take it back, but I really hope that he takes the time to think about why he did that, and hopefully he'll learn from it. Namely, not to EVER be vulnerable in front of Katherine.
4. Do you think Damon helped Caroline just to attempt at making amends with Bonnie or do you think he honestly cared?
Damon cared because Elena cared. Bottom line is that he never would just walk into a hospital and give his blood to some girl he used to use for blood. She's connected to Elena, so he did it. And he doesn't need to make amends with Bonnie, IMO. She needs to do some apologising.
5. Do you think Damon knew Jeremy had the ring on?
No! It really bothers me that people are backing up Damon on what he did. I'm still Team Damon, but it doesn't make me a bad fan for making what he did his responsibility. Stop blaming Elena and Jeremy, and start putting the blame where it's due.
Now, back on track. Damon didn't know Jer had the ring on, or else he wouldn't have been going on about how Jer wanted to become a vampire.
Jeremy
1. How do you think he'll react to Damon killing him?
Remember how Jer had that conversation with John? About the family legacy? Sure, Jeremy was happy to tell John he was wrong, but then that same night, a vampire he sorta-trusted killed him. And this is after he walked into his sister's room to find her upset, and Damon holding her wrists. Personally, I believe this is what will make Jer into the new John. That, and he's been hurt so much by the vampire world, that it's easy to forget about Anna's kind nature, and the Stefan's caring relationship with Elena.
2. With him failing at turning himself do you think he'll try again in the future?
As I said in the question above, I really think the Damon thing will turn him to the other side. I don't think the reasons he wanted to become a vampire are as clear to him now. They're being blurred as he's being taken more into the world of dangerous vampires. Face it, the only vamps he remembers knowing is Anna, Stefan, and Damon. Sure, Damon's been dangerous the whole time, but he's never done anything like what he did in The Return.
Caroline
1. Do you think she'll come back a vampire?
Haha, yes.
2. If so how do you think she'll react?
I think she was a character primed and ready to become a vampire! She'll be awesome
She will probably be angry at Elena for keeping a secret from her, probably one she thinks is cool.3. If she dies what do you think her mom, Bonnie, and Matt will do?
Can I change this to, What will Liz, Bonnie, and Matt think of a vampire Caroline? Let's start with Liz. She's believed her whole life that no vampires are good. They're all evil. She has them in this one category. And her relationship with Caroline isn't good, so that will add a whole new dimension to it. I think this change will force her to rethink her ways of life, and also the life she wants to have with her daughter.
Bonnie, I think, will blame Damon. Even though it's 100% her fault. She's the one who asked him to give Caroline the blood.
Matt will finally find out about vampires! And his werewolf friend is, I'm sure, soon to come. Maybe episode three, perhaps (Bad Moon Rising)? Hopefully he'll try to keep an open mind. I definately think there will be some kind of conversation between him and Elena, because they've both been in that situation.
Tyler
1. What do you think about his Uncle Mason?
Mason seems...I don't know. He seems like he could be a good mentor for Ty, but I also see this side to him of a very bad mentor. I'm keeping my mind open
2. Do you think he'll truly try and help Tyler?
Help? Again, we don't know enough yet. He could seriously hurt Tyler's way of dealing with this.
3. S. Forbes said he doesn't believe in the council and wants nothing to do with it. What are your thoughts on that?
I think that he didn't view it in the same way Damon did (as a way to keep tabs on him) and he's got enough to worry about.
Note on Tyler: Someone said something somewhere (lolll) about that drink Tyler had being werewolf-related. They made the point that the Mayor wouldn't have any reason to have alcohol hidden in his study, because it was always so available to Tyler. Also, when Mason came in, he was rude to Jer, with no prior meeting or contact between them.
Elena
1. After Elena finds out what happened between Damon & Katherine do you think she'll have any regret or remorse for Damon?
I think...she'll understand. If she doesn't find out, I would be surprised if she doesn't try to hurt him in some way. But even if she does find out what happened, it doesn't make what he did right. But she'll understand, and accept it that he was more upset to begin with then she gave credit for.
Stefan
1. After this incident with Jeremy do you think Stefan will actually fight Damon this time?
Nooooo. As I said in the first question, I think we've seen exactly what reaction we'll get from him. Elena's upset, so I think he'll do some digging as to what made Damon go off, but besides that I don't think there'll be any drama in the Salvatore house for a while. He'll be too afraid Damon'll go off again.
2.What do you think his plan will be to get rid of Katherine?
I honestly don't think he has one. I think his plan right now is to keep Elena as far away from her as possible, and not to fall into her trap. Oh, and to try and keep Damon out, too. Sooner or later *cough*episode4*cough* he'll try to find out what her plan is. Damon, I don't think, is interested in her plans anymore. He's done for a few episodes.
Katherine
1. Do you think she honestly came back for Stefan?
Maybe, but that's not the only reason.
2. Do you think she knew Elena looked so much like her?
Yes! She talked about Isobel earlier in the episode, and it sounds like Elena is part of the reason she came back, considering all that Kat bothered to find out about her.
3. How do you think she'll introduce herself to Elena?
In some completely unexpected way, making Stefan (Damon?) watch and know how powerless they are to stop her from getting what she wants.
4. Do you think she knows Pearl & Anna are dead? How do you thinks she will/did react?
Good question! I don't think she'll care that Anna is dead, but I think she tried to kill John because of Pearl. After all, she didn't take the ring. And the news of his death will come within a few episodes, I think. Stefan was right when he said Kat would try again.
5. Katherine knows the Salvatore brothers well. Do you think she intentionally hurt Damon, knowing he'll have violent reactions, and count on him loosing his mind as a push to cause some damage?
Hmm...I don't think she was planning for him to go off on someone else, but she absolutely meant to hurt him. How could she not, considering the way she said it.
Bonnie:
1. How do you feel about Bonnie accepting Damons offer to help Caroline?
I was kinda shocked! I didn't expect her to give into that risk. It makes me think there's more of a Caroline/Bonnie friendship then we know about.
2. How do you think her retaliation to her Brain-Pain game not affecting Katherine will go?
Ohhh I hope she tries. I'm tired of Bonnie, and Katherine knew Emily well, she knew what spells could be used against vampires, and how to avoid them, I'm sure.
When she went home, she just looked so tired of her life, and I saw an echo of what we saw in season one. I really think it could happen soon.
