I like to think this is when they’re one and the same, like in the cosmetic. SecOp feeling the half of his face start to get distractible and not wanting to finish the round they’re working on.

He manages to get them back to the privacy of their base, begrudgingly playing along with his other half. He's a bit embarrassed, but still tries to make the other happy, despite his grumpy disposition. He might finally object as soon as a pacifier or diaper comes into play (you might get him to use the paci as long as he gets to angrily bite his half).
