[X] Play Sneaky Diplomat
-[X]Note that fighting here will frighten the people around them, people that she's supposed to be protecting.
--[X]Point out that the place she's treating an arena has people living in it.
---[X] Invite them to take a tea in a calming location, or duke it out in more anonymous place.
----[X] Point out that fighting won't make White Knight go away.
-----[X]Unless she wants to kill her, of course.
------[X] Transform only if battle keep going or you're in danger. You're not Miss Unknown Newbie anymore, if someone finds out you're here, you could find yourself with a kill team in town when you're there, or worse, when you aren't.
[X] Transform and point out to both of them: "Excuse me you two, wouldn't it help to, maybe, take this outside first? This town wouldn't fare well with such powerful Magical Girls fighting within it."
-[X] Once that does happen: Catch Red Knight's attention by stepping in between her and White Knight. Proceed to tell her that you wish for her to stand down and for you to hear her part of the story. Then tell White Knight to not interfere and to wait her turn.
--[X] If Red Knight thinks that you (Solid Core) are lying/bluffing about what you just said: Tank Red Knight's sword (Her normal attacks, not R.E.B.E.L.L.I.O.N.) to properly convey to her (Red Knight) that you are serious about what you just said.
[X] If Red Knight refuses to leave the area and starts attacking: Do the above and tank her sword strikes to get her to listen to you about hearing her part of the story.
[X] Transform so you don't get collateral'd
-[X] "You know it was Rei who got San to come back, right!? I just stood there and looked Moe!"
--[X] Explain who Rei and San are if asked.
--[X] Stand there and look Moe. Interfere if someone is going to die.
[X] Transform so you don't get collateral'd
-[X] Get between them
-[X] "Okay time out, what happened here anyway? I just got dragged in to act as mediator"
[X] Transform and stand between the two, try to get them to talk it out.
-[X] If either of them attack block them, strike back if needed!
—[X] Try to get Red Knight's side of the story.
[X] Transform so you don't get collateral'd
-[X] Point at Red Knight and shout at her to not be such a jerk. Say you've fought Goddess Grey to protect your friends and you'll fight her too if she starts something.
-[X] Try explaining that you've both lost friends these past few weeks. If Red Knight really wants to part ways you won't stop her, but understand that's where Kat was coming from and why you wanted to help her. Tell White Knight to stop talking if she tries making her own arguments, it's clear Red Knight doesn't want to hear it r
