Why?, she can just tell him that she can see things and prove it, then ask for help for ther mother. Or just have doubts after everything that happened cos of that family. May be just do some research about her ability or something like that and think in a better plan for her mom and her... I'm just saying...
Wait, am I missing something??? I thought that our dear uke do know that Jay was the guy from before, when the uke was wearing a bunny costume and shows his back tattoo to Jay... I was wrong? I misread? Σ(  ̄□ ̄||)
Nope, at that time he's just trying to catch seme off guard because (I can't remember the details much) I think the seme was avoiding him or lied to him so he went there to show that he knows seme is lying and he wants to confront seme for playing with his feelings or something? I'm not sure, it's something like that.
And that's where seme confirmed that he's the bunny guy, but at uke's mind, he just confronted seme. He didn't know until chapter 80...
I LOVE THE REACTIONS SO MUCH OMG I LOVE THEM!!!
