bath time?

This pic is for my friend Sfmk2's fanfic"Time Diver".In this story,Scorponok devised a time machine,sent Optimus Prime and Megatron into past and made them archivist Optronix and miner Megatron again...and then they must ally to defeat Scorponok.
This scene happened when miner Megatron(with the soul of lord Megatron inside his body) fled away from Energon mine and found archivist Optronix(with the soul of Autobots leader Optimus Prime inside his body).
Optimus was helping Megatron do some cleanness.The characters on Megatron's chest read:"work safety"
