This is how Twilight and Optimus Prime talk goes in My Little Pony Transformers: Revenge of the Fallen.
[Twilight and Optimus arrive in clearing]
Twilight Sparkle: What did you want to talk to me about?
Optimus Prime: I'm sorry, Twilight, but the last fragment of the Allspark was stolen.
Twilight Sparkle: Like what? Like Decepticons stole it?
Optimus Prime: We placed it under equine protection at Celestia's request... but I'm here for your help, Twilight, because your leaders believe we brought vengeance upon your planet. Perhaps they are right. That is why they must be reminded by another alicorn of the trust we share.
Twilight Sparkle: This isn't my war.
Optimus Prime: Not yet. But I fear it soon will be. Your world must not share the same fate as Cybertron. Whole generations lost...
Twilight Sparkle: I know, and I want to help you, I do.
Optimus Prime: Twilight, fate rarely calls upon us at a moment of our choosing.
Twilight Sparkle: But I thought you cared about other living creatures.
Optimus Prime: We do, more than you know.
