I think it'd be interesting to see, a more Genndy-type romance than what we've gotten in Hotel Transylvania, but based on the episode descriptions, I don't believe it'll happen because there isn't enough time:
Episode 4-Jack and Ashi escape a giant monster gut
Episode 5-Jack manages to lose her and goes on a solo adventure where he gets to be a hero again by saving a bunch of people from becoming Matrix batteries
Episode 6-Ashi searches for Jack and meets some of the people he's helped
Episode 10-Final Battle
So that only leaves you with 7,8, and 9 for them to reunite, bond, get a buddy cop thing going, and then maybe hook up.
