Walt, whose cough is pretty constant, talks to Jesse about going to college for business and marketing, telling him he’d be a whiz, and even self-awarely brings up that he’s just making conversation.
Depressingly, the scene ends with Walt telling Jesse that he was lucky because he didn’t have to wait his entire life to do something special.
In the flashback, which was set during Season 2, Jesse and Walt are shown going to eat breakfast together at a hotel, where Jesse is in love the salad bar, including the pineapples.
(That’s about all one could have expected from this cameo, after all.)
