As I read it, there was a perfectly natural progression (at least in Gil's mind) from the disease/poison resistance program to "amusing Sparky quirks" to the waffles. (As it seems to me that Klaus found time to give Gil some training in person even while he was incognito, I wonder if some of that involved being quarantined together in cases of contagious diseases that they didn't have a vaccine for....)

I actually have a mini-theory that Bill and Barry liked Klaus in part because he kind of reminded them of their mom. The sense of responsibility and all.
