This is how Soundwave reports to Starscream and Hardshell goes in Sparkling Problems.
[Soundwave enters the room where Starscream is with Hardshell]
Starscream: Soundwave, what is it?
Hardshell: He has some critical information, my liege.
[Soundwave plays a recording of Starlight's voice]
Soundwave: (with Starlight Glimmer's voice) Who knows what Starscream's done to the Autobots by now? We have to save them.
Starscream: Ah, Princess Twilight Sparkle's student.
Hardshell: I was thinking, my lord, why just capture the Autobots when we can still surprise the ponies?
Starscream: Good idea, Hardshell. [to Soundwave] Soundwave, increase the security. We are going to have un-invited company.
Hardshell: Shall I provide back-up?
