When you’ve had enough because this is a serious situation
i can’t even imagine what Soundwave yelling sounds like because he’s often seen as the “silent one”, or at least someone who doesn’t get visibly emotional, like i don’t think he’s ever yelled in a tv series or movie…
so now i like to think that it’s actually very loud, very resonating, very heartstopping, where everyone and everything in the room freezes because shit just got real
