Both battles were written really well and I don't have much to add on either. Error's was pretty long, but it build a lot between the characters and added depth to his heroine, so that's fine. The battle was choreographed very well, and despite personally having a Mr. Serious at the moment, ending on a joke is a fantastic way of winning me over!
Alph, I think you're doing a lot of creative experimentation, but I'm not super sure battles are the place to do it. The flow was there, characterization was there, but... I don't know, man. It's kinda like for the past couple battles, you haven't been putting your characters in any real danger. With George, David seemed off sight just setting up the dominoes to descend him into madness, and here, she's drugged on sight by Al, bound when she meets David, unbound with David and then there's David again perfectly fine after she stabs the first one. You say outright that she's an assassin to kill him, so bias is against her (your protagonist, not bashing, just the way it is), but when Party A is in no danger and doesn't want to kill Party B, there's not a whole lot of... tensity? that can come of it. I don't know man, I feel like there weren't really stakes here.
Maybe that's just me.
Great job though, you guys!
