It’s like Soundwave helping Starscream out after losing his T-Cog.~
Y’know…I think Starscream and Soundwave did leave each other on good terms. Like Starscream trying to articulate his feelings about turning over a new leaf with regards to being loyal to Megatron and Soundwave listening. I could maybe see Soundwave dragging Starscream back to Megatron, only to play back that old Starscream attempt at articulation to show that, yes, his Second-in-Command was ready to change, and then Airachnid screwed him over…someone I think Soundwave would still be displeased with, after her obvious attempt at mutiny. So, like maybe two birds with one stone there.
