Is there something beyond just two girls cutely brushing each other's teeth here? I suppose it's a meme or whatever, but is there additional context which makes people feel it's weird that I'm not aware of?
It's often drawn as something cute for characters to do to each other.

Is based on nothing, A2 absorbs 2B but that's that, it's not like they can have an relationship or anything since 2B is inside her but no longer can hold a physical (android) body
Nah nah nah, Yuri is into Mako. She's just really weird with Tomoko. Nemo seems to have completely lost it in the recent chapters and might shoot up the school at the rate she's going though.
