I also wonder if The Machine is going to contact John too, since he was an admin together with Root. Or if this is something that only Root can do, whatever it is the Machine wants. Or maybe it just wants to help Root getting out of the hospital because it wants everyone in its little family to be happy?

Seriously, we need a better name for the Machine, now that everybody knows that it's sentient. It's a cute duckling of superpowerful god-like entity, it deserves a proper name.

(I was re-watching Firewall yesterday, and it makes me so happy that the first one to address the Machine as a person is John. It would have never occured to me that it could be sentient, and yet he just walks right to it and asks for a helping hand.)
