"I don't know, Drift." If Arcee sounds frustrated, it's because she is -- about all of it. "I don't know how this works, either. All I know is that it's Orion, not Optimus, who's on this planet, and Megatron's put his head in a spin. I talked to him as best I could, and I think I gave him a lot to think about, but...I couldn't force him to stay here. I wouldn't. I don't think Optimus would've wanted it that way."
