Jack didn't climb all the way back to his feet, insteady he stayed on one knee. He tightened his grip on the hands in his, and fed everything he had into the Master's pull, silently encouraging others to do the same. He was through with this too, and he was one stubborn son of a bitch. If the castle brought the Master to them, or just exploded into a cloud of nothing, or something between, there was no way he was giving up.
And that the Master had responded to them shoving mentally, was a damn good sign as far as Jack, and his cracked ribs, was concerned.
