It's almost certain Soundwave recorded every last second of Airachnid's betrayal in the last Season 1 episode. And he most certainly will play the recording to Megatron. Megatron's not going to be too happy with Airachnid. So what will he do with her? Will he punish her? Will he even go as far as beating her to a pulp like he did with Starscream? Or will he play nice for once in an effort to convince Orion Pax of his "benevolence"? I don't know if he wants to viciously assault his troops if he's trying to win Orion over to his side.
