Wondering something about Walt's relationship with Jesse *Series Spoilers* Walt and Gus were bonding in season 3, Walt seems to be enjoying what seems to be an amicable relationship with the big drug dealer this time, and even enjoys cooking with Gale.

So my question is, why wouldn't he want to give up Jesse when Gus wanted him to, why was he so insistent on protecting Jesse, especially considering how evil Walt becomes by the end and even just as recently as poisoning a kid, to be so attached to Jesse. In spite of their constantly strained and rather dysfunctional relationship. 

His strange fascination with wanting Jesse always confused me; instead off him heading for greener pastures with more competent people that have a more evolved vocabulary than just "bitch" he chooses to remain with his old buddy from the beginning of his bad breaking days of cooking meth.
