^the Twins? the page floating around tumblr with the cast list for episode 23 had both Max and Charlie both listed...Ian was in between the two. ( at least from what I remember...been a bit since I saw that post)

I think bc of that HBO thing they leave during 3b, bc i think i saw someplace the twins asked for the possibility of them to come back so they would just have them leave and not be killed off

if they said that i dont blame them but not a really a fan of their characters. the new series for HBO could end up canceled or they get killed in it so they might need a fall back plan. if the show gets canceled or they get killed in it they wont be able to come back until season 5. season 4 will problay be written in a couple of months or less so jeff wont have time to write them in it. 

I don't think Lydia can turn into a vampire.... being a banshee and all. If she's immune to the werewolf bite and the kanima venom, I'm willing to bet she's immune to vampire bite (and I'm also willing to bet vampires wouldn't want to feed on her anyways with blood like that.)

That's all entirely speculation of course because there are no vampires on Teen Wolf. (Yet?)

Well, this just got shut down.

well Ethan could come back, but I doubt they will do that.

I think they only killed Aiden and not Ethan because Ethan always felt like his brother was holding him back.  Now Aiden dies rightfully deserving every1's redemption, and Ethan gets to live his life

Actually, what the OP was saying was pretty much proven. Aiden's last words were "Lydia never thought I was one of the good guys anyways." Sounds like Aiden loved her to me.

well, this thread looks stupid in hindsight...
