"Oh yeah?" KF scrambles after Robin, stomping down the hallways to follow, gut burning like it's been lit on fire, hands shaking because he's so angry and he's hurt and he wants to just lash back out and make Robin hurt as bad. "Well, you can still use Wally if you want, which is hilarious because I didn't even tell you my secret ID! You just rooted it out yourself! Apparently you deserve to know everything I don't tell you, so go right ahead! Enjoy yourself!" And Kid slams their bedroom door for Robin, standing in the hall, staring at the door and shaking before turning on his heel and darting out of the cave as fast as he can.
