I really think the movie is what has elevated Domino. She was gonna be in Deadpool, so having her in Weapon X may have been Marvel's way of giving her some spotlight, Same reason Gail got to do her solo. Otherwise, she was in & out at random like Monet prior to DP II.
The movies are usually good for elevating characters, IF their character is popular on-screen. And sadly, Domino has turned into a doofus in her success, like Deadpool did. Soon, just like DP,she's gonna be known for being a comedy relief character.
We don't know. All we got is Jordan D. White saying there MAY be plans for Monet. Far as Uncanny 9 goes, Frenzy wasn't on there either I don't think. It may depend on where everyone is coming from. Some were shown getting Jean's message & on their way. Others seemed more preoccupied, like Frenzy working on her, or a, car. Monet seemed like she was already in a fight elsewhere.
Before this splash page, she was white last we saw her.

So she's gonna go back to flip-flopping around. She did it constantly in Weapon X where she was either light brown or fair-skinned.
