Also did anyone get that snow falls in Miami thing?
I got a theory! Remember how Molly's parents were killed and frozen from Sylar? I think maybe Molly's dad or mom had the cryokinesis power and he froze the tsunami or something. I dunno.
Adam is pretty obviously just immortal-esque, due to not aging, etc. I don't think he could learn to heal others; they're totally different. Candice, Matt, and Morrie all had very similar powers but different areas. Candice was good at illusions, while Matt was good at reading the mind, while Morrie apparently specialized in 'nightmares' and the like. They all deal with messing with other people's minds, so that's different from cell-regeneration, etc.
