The Master was right, Jack was heading for him within seconds, and had full expectations to slam him against the unbudging TARDIS doors to knock him down, but was met with the Master's fist instead. It didn't do much to stop him, but he was somewhat dazed when he slammed his shoulder hard into the Master, sending him crashing into the doors he so desperately had tried to escape through.

With his attack complete, he struggled to pull the Master's hands behind him and yank them upward as hard as he could, just so he could bind them together with the Doctor's tie. "You are stubborn, aren't you? Stubborn and stupid."
