The guy is a good actor. Vince Gilligan said the way he plays the character has really shaped how the writers write him. The nonchalant way he goes about his business is just cold. Like there's nothing there.

I can't remember where I saw it but there was a rumor online, before the last episode aired, that Jesse would survive the shootout and be forced to cook for Toddy's uncle's crew. That ended up being true. Another prediction from the same place said Walt would rescue Jesse. So we'll see...

Incidentally, some have said that Walt knew the cops were listening on the phone and he intentionally talked to Skyler that way in order to take suspicion off her.
