For all we know, Claire is immortal too.
i think she is since it's the same power. i also think Linderman is alive and has the same power. like with matt's power the cellular regeneration could be something they can project which Linderman used to heal.
Wasn't the back of Linderman's head blown off last season? Pretty impressive (or lame) if he can come back from that.
well if it just an advanced version of claire's power then he could regenerate. it just seems odd to have all that build up and then kill him so quickly. i got the impression he'd be back.
I must admit that I too find it a bit odd, and lame, to build Lindermann up for so long and then just kill him off. I don't think he'll be back, but it was a shame that he was killed.
