Do you think Alex is dead?

Pandemonium is still yet to come out in march. i will say however, i've read the excerpt and it doesn't confirm either he's dead or alive.
for Lena, she does believe that he might be alive. though for the most part, she doesn't want to have the memories of him slowing her down from her new goal, instead she tries to make hope her strength in adapting to her new situations.

and also, i heard there might be ANOTHER GUY in Pandemonium, which is why Alex should not be dead!
i hope so..

I think he's not dead because it won't be the same without him. Maybe he's been "cured" and Lena will come to rescue him and make him feel again.
But I really hope he isn't dead..
