That seems like an awful lot of spark to have suddenly appeared after two years of not seeing each other preceded by what was probably a very hurtful argument.

I didn't get the impression that there was so much anger between Kara and Lee. More of a...convenient non-communication. If they had not physically moved apart, I think they would have kept their old ways of interacting. (I didn't get the impression that Lee was assigned to instructor duty - he was probably in a different but local unit? I think?)

In contrast, Lee and Adama definately had a falling out.

In both cases, I think, enough time has passed that Lee is making *new* relationships rather than simply renewing old ones.
