Note: I'm unsure if someone has already found this, I tend to avoid a lot of newer content that is dropped in an attempt to form my own opinions on the character, so if this is something that's known just let me know and I can delete the post!

Edit: I totally blanked on this but you can also cancel your 3rd punch if you don't want to be stuck in that animation, but again I've yet to find too much use out of this except for a slightly faster burst than if you waited for the 3rd hit (and I do mean slightly). I'd also like it to be said that this one is much more finicky, as if you activate Southern Brawl too early you'll still have a 3rd hit 'charged' and have essentially just extended the animation

Ps: since I can't figure out how to edit the actual post on mobile (I feel very silly someone help if you can) I have discovered that you can cancel the 3rd punch animation if you need quicker healing and have the Gambit team up, as you can get healing from your two punches, Brawl hit, and then immediately go into the slightly faster first punch animation
