Originally, Shockwave would have called his relationship with you illogical and borderline insane, but as you sit on his shoulder, you resting in his neck cavity, he can't deny the feeling of calm.

He had once thought humans were timid pests, but his own was more a warm pet who could run errands or be an extra pair of servos- hands.

You're his assistant for experiments, and his courier/spy among earthly kind. and for some reason, cuddling into his neck as he works seems to make his productivity rate for written work skyrocket.

It's only logical that he keeps you around.

Shockwave shifts a bit, and you don't catch his single yellow optic glancing down at you via the reflection of his datapad. "Mae, go fetch an Energon injector for myself, and some human fuel source you stocked."

If Shockwave had a sense of humour you'd giggle at the use of the word 'fetch', but you know he didn't have any alterior motive behind that word selection.

shockwave had been oh so considerate and had a small habsuite area of human amenties built just for you: a kitchen, bathroom, bed, and even an exercise room.

When you return from your little quest, Shockwave leans forward in his seat for you to climb into his servo as he lifted you back to his shoulder, and waits patiently to insert the injector (the size of yur calf by the way). Due to his lack of an intake, the injections are nessesary to keep him functioning.

When you're done attaching everything and turn on the injector, Shockwave lets out a low sigh. You're not sure what emotion the sigh is meant to be, but relief is the most logical option.

Since you both recharge and consume your natural fuel source at the same time, Shockwave has taken to using you as a living clock to see when he needs to actually take care of his frame.

Unsurprisingly, he has trouble tearing himself from his work.
