Huh, that was really interesting. They're SO different from each other. Jimmy still has some of the climber-dirtbag vibe, even though he's not really anymore, whereas Elizabeth Chai has a sort of high-society feel (I don't mean either of those terms as insults). It's sort of surprising to me that they ended up together, but it seems to work really well for them.
Also, I've seen clips of Alex on the wall about 100 times now, and it still gives me chills.
