I want to say yes.
I sort of tried to not ship this, but...Okay, fine. Guilty fan. I like this couple and no one can tell me otherwise. -_-

I'm not too sure myself. But I feel like it was kind of hinted that they were; I mean between the bit with them going for the hug, Warmonga taking jabs at how "you were threatened by my arrival", Kim's "see, you do care", and eventually the flower hug in the end. I mean up until that point the flower-vine-thing, only moved at Drakken's command.

I ship it
