This is how Thunderwing in Twilight's mind goes in Cybonic Plague.
Ratchet: Optimus we have the formula. Disconnect Twilight now!
[He does so]
Thunderwing: You were watching. You tricked me!
[The scene begins to crack]
Thunderwing: No! Take me with you! TAKE ME!
Optimus Prime: Hurry Twilight.
[Twilight comes to]
Queen Chrysalis: What in! Intruders!
Arcee: Allow me.
[She fires at the cable and it explodes]
Queen Chrysalis: It was the inevitable outcome.
[Soundwave points to the direction the Autobots and Ponies were]
Queen Chrysalis: Of course, it would be wrong to allow Thunderwing to perish at an Autobot's hand. Starscream.
[Starscream reconnects the cable]
[At the Changeling Castle]
Queen Chrysalis: And how is the patient doing today?
Starscream: Funny you should ask. Not sure what the 'bots and ponies did in there, but Thunderwing's registering zero brain-wave activity.
Queen Chrysalis: Meaning?
Starscream: Physically, he's stable, but now there's no one home.
[At Canterlot, everyone is still celebrating to notice Twilight's eyes suddenly turn purple and sees Thunderwing's corpse in her mind and Thunderwing's eyes: Thunderwing is now occupying Twilight's mind]
Thunderwing: [in Twilight's mind] I'm out. Or should I say in. Ha ha ha ha.
