[Keeping Starscream from doing something potentially foolish that's what. The shove, despite their more equal size, doesn't really do much; Jetfire still has more mass.]

And what if it doesn't? You... We have no idea of the capabilities of whoever is in charge, and apparently other things are altered than just, say, our size! Like weapons.

[Jetfire frowns and this time grips both of Starscream's upper arms, turning him around and more to hold him in place than really hindering him from aiming his arm cannons at Jetfire.]

I think I'd survive, though, considering you've already done so, besides whatever alteration may have been done. Can you for once not rush into something? I know you can plan, and shouldn't this situation be one, if any, where to use that and not attack the first best target that presents itself?

[There's nothing pleading here, merely stern reasoning; pleading will not get you anywhere with Starscream, and worse, demanding would have the Seeker being contrary. Jetfire's worried, the situation has him on edge, as well as the claims for why they're here, but Starscream is, perhaps amusingly, something to focus on.]
