[At this point, he expects Monika to yell or screech at him. It's so undeserved, but no matter how many times he reminds her, she still couldn't help herself from becoming a screechy little raptor. So, Soundwave prepares for pain since his hands are busy carrying Monika.

Anytime now.

Aaaaanytime.

Ah, there it is. He still winces in pain, but if he hadn't prepared himself for her scream, he would've dropped Monika onto the floor. See how considerate he is that he's willing to hurt herself than let Monika be hurt?

He rolls his optics at her feeble attempts at a protest. No matter how loud and whiny she's being, he won't back down on this. Hell, just look at her not even moving her limbs much... He can imagine her bones are straining since she isn't doing her usual flailing. Also, cubbyhole?]

Do not call my chest compartment that. And stickers? How terrifying, Monika.

[Wow, stickers. It's not like he has access to another form that could help with peeling them off (Although it's going to be irritating as hell to peel them off, so he dearly hopes that she doesn't go through with her dumb threat.).]

I will make it up to you. [There, a compromise] Whatever you wish to do, you are free to tell me and I will do it, except for getting you back inside my chest.

[That is a firm big NO on that.]
