At some point of his work in the Library, Roland noticed Angela is...well, less 'friendly'. As in, she's alot more gloomy all the time. So he made it his mission to cherr her up, for his own sake

He tried EVERYTHING; To get her drunk (she is still an AI, so it was impossible), play board games and what not.

Then...an idea clicked. Karaoke. Of course! Angelica and him used to do it back then!

So he, unfortunstely, went first to...well, break the ice. After getting her in a room that was away from the rest of the Librarians, he FINALLY got her to relax a bit. Hell, he even got her to sing! And dress up! And out on unnecessary, but cool, sunglasses!

Netzach: "Singing huh?"

Netzach whispered behind the door, slothing on the table as they spied on the two of them

Malkuth: "Shhhh!"

Tiphereth: "You'll ruin our hiding spot!"

Hod was supporting Tiphereth on boxes so she can peek at the glass above the door, and Chesed was standing on a table to do the same

Binah, obviously noticing the commosion, simply turned the doorknob, causing all of them to fall in a room. Roland and Angela's reactions were...wastly different. Mostly because Angela nearly kicked them all out
