Oh, right. Of course Karkat wouldn't know about that relationship -- it had been dissolved before he even arrived in Panem, having succeeded in mediating the issues that necessitated it be entered into in the first place.

"You're welcome. I'll always be here to help, whenever you need it. And -- ashmates. I should probably tell you, it was just never relevant before now. The Initiate and I used to have a much more volatile relationship and while it wasn't caliginous, it was detrimental to most anyone who was close to either of us. Terezi stepped in to mediate between us and through her we reconciled our issues and became close enough to flip pale."
