Don't leave before I get there I'm coming after you for not showing cake. I'm hijacking one of those boats you pedal with your feet as we speak. Gimmie a month
It would be the same concept as Bayman x Zack, cept Helena would be trying to teach Tina to be a lady and Tina would be trying to teach her to have fun.
I can imagine Helena trying to teach her to curtsy or bow. And Tina teaching her to move her hips. Or they can do the independent woman thing and both cross their arms at the downed opponent.
I honestly think they have so much in common that I find it odd why they haven't had interactions. Both don't have mothers anymore, rich and has a profession in music (Helena as an opera singer and Tina as a rockstar).
