Honestly, she doesn't even need a reason since it's not any of his business (and it's not like he directly told her about Nene either), he's just being a nosy and bratty pain in the ass lmao

Although THAT SAID, if she needs to talk to him about her current stuff with her parents, he could lend an ear?? Of course, if this Disturbance has taught him anything, it's that he's seriously out of his depth re: parent problems, but at least he can give her somebody to vent to 8'|
