You were a minicon, and Shockwave's assistant. You helped him with creating the Predacons, a very time consuming and difficult job. Megatron trusted you both, which kept you going, but it was still not enough to assure you.
Shockwave was used to you getting discouraged over your failures, and tried to cheer you up the best he could, considering he didn't feel much emotion wise. He allowed you to sit on his shoulder, an easy thing for the both of you to achieve with the size difference.
It gave you a better look at what he was doing so you could help in, and in turn, comforted you when you started to doubt yourself.
He focuses on what he's doing at his desk, you perched on his shoulder, legs dangling over his large chestplate. He reached up and scratches under your chin, his mind elsewhere as he does so.
"Are you writing this down?" He rumbles out, glancing up at you and the datapad you're holding.
