After going down 2 games to none with best gal, I felt like I needed to do something that was just fun. It's why I came back to the game after all. So, I literally said "f*** it" and played the 3B mirror.
Turns out I can learn a character mid match. Once he switched to Ven, though, I figured I'd give Gwen one more go.
Better luck next time.
GGs d00d, and good luck the rest of the way!
