He hears the thump and his gaze darts towards the airlock. He can see a flash of orange through the different equipment and crates in here.

"I sealed the airlock and put on the security seal. Don't bother trying to steal the control at superspeed, it's got a passcode and a retinal lock." It takes time to scan someone's retinal pattern so the tech won't keep up with Grif's superspeed, if he tries to get a read from Rich's eyes. "Oh, and the rest of the station? Is sealed off. No air in most areas besides this room."

Rich walks around the equipment, taking his time. There's no need to rush this, the stargate is charging up, and he knows Grif probably already contacted the team, but even if they get here in time, it's unlikely they can stop it.

And now that they've revealed the Truth to him, he wants Grif to understand.

"There's no way out. It's just you and me." A pause. "Which is kind of fitting, if you think about it. It was just you and me when we faced the Surfer and Stardust, remember? You caught me when I fell. Now it's my turn."

He holds a hand to his chest.
