The circumstances that had brought each of them to this Earth were different although neither seemed too worried about being there.
Steve thought that someone named Lang would be showing up eventually and focused on trying to help out wherever possible.
Clark seemed to relax and not worry as much about breaking things; he volunteered to help the Dinobots work on controlling their strength.
The troublemakers in the Autobots thought they should be giving Megatron the trifecta of disapproving looks not them.
Optimus just welcomed the company of two who truly understood when he asked them to call him Orion.
