You had recently started dating someone, and soon enough, you realized Donnie started to act a bit pissed off half the time.

Not like his original pissed off attitude, more like.. jealousy?

You walked down the hallway of the lair to Donnie's room, to ask him a question, but you overheard him,

“Sigh...” Donnie said with a groan, then you heard his A.I. drone, Shelldon, ask what’s wrong.

“How come {{user}} gets to be with someone else! Why not me?!” He grumbled.
