Aita For Being A Weirded Out By My Parents New "friend"

So long story short my parents are in their 60s. In the last few months they've befriended a girl who works in the same area as they do (a 20 year old female). At first it seemed more like a work friends relationship, when they're in the same sort of area they'd talk / hangout / she'd bring them things she bakes, she's taking some sort of baking course so she's always giving them her leftovers from assignments.

At first it was April bringing them things at work.

This turned into April going places with them after work.

Then it turned into April driving out of the way by 40 minutes to visit them at their home.

My parents also for some reason tried to set this girl up with my nephew who's the same age, he completely shut that down pretty quickly as he's not her type at all despite my parents really trying to push it on him...

Okay that great a new friend is exciting, albeit the age difference is a little bizarre.. maybe they're giving her a bit more attention, fine

I go over there with my nephew one night a few weeks ago, April is there.

Another time my wife and I dropped by without warning, April is there.

I video call me parents randomly throughout the week and she always seems to be around.. at work or outside of work, oh "say hi to April!" Suddenly she appears.

Well the straw that broke the camels back was that my parents were having the whole family over for Easter today and you guessed it.. April was there - not only that but the whole night was basically about her. April did this, April did that. I don't think my parents spoke more than 10 words to anyone else in the room. It was super awkward for everyone involved - she stayed all night. My boy actually opened his Easter basket in the corner of the room whilst my parents were in convo with April, this normally would have been something they'd make a big deal out of, maybe bring it out and pay attention to him for a bit while he opens the gifts they got him. Not today.

Weird comments being made, my mom was talking about a gift she's going to ask for as a birthday gift all of her kids can pitch on, April explained "guess I'm unadopted".

Something about how she's collecting daggers because they're easier to stab people with and the wound won't heal ?

Anyways I spoke to my parents when April left and explained to them that having her over during family functions makes it awkward and they didn't want to hear what I had to say at all - my mom made me out to be the bad guy and told me it's "controlling of me to not want her to have friends". This is when my wife chimed in and kind of explained to them that the whole thing is super weird and that it seems like April is just inserting herself.

AITA for being uncomfortable and getting bad vibes from this girl always being around? freaky how obsessed they've become and my true crime watching brain is telling me she's trying to take out life insurance policies on them or something lmfao that how weird it seems to me
