Panel 1 - Shockwave looking displeased as he crosses his arms against his chest

Shockwave: "Please don't tell me you're backing out of this because you're embarrassed to be seen with a gay mech..."

Panel 2 - Megatron putting his hand up to stop Shockwave from speaking, a look of shock on his face.

Megatron: "NO! No... no, it's not that. I'd never be embarrassed of you, Shockwave."

Panel 3 - Shockwave having let his arms fall back to his sides, a little slouched.

Shockwave: "Then what is it?"

Megatron: "Argh, it's nothing. Just let me get suited up."

Panel 4 - The door slamming closed as Megatron makes his way into the bathroom

Panel 5 - Megatron smacking his forehead against the wall in anger and frustration, jaw tight.

Megatron: (inner thought bubble) 'Damnit, if they say a single word to me...'

Megatron: "FUCK!"
