If our characters were in an OT3, who would be the third character? Character list here!

Eliot.

Hardison, Parker, and Eliot are practically already an OT3

Yeah, I didn't even think of mentioning it because it's be WAY TOO OBVIOUS

Eliot already feeds them and punches people who try to hurt them

Yeah, having them as an OT3 is so nondifficult I'd rather not even point at it. Because "LOOK AT THE OBVIOUS!"
