When everyone passed through the portal, something... strange happened. They were in a void of whiteness. At the other end was the blackness of space, The Combine overworld clearly visible.
It was collapsing in on itself, portions of it being sucked in and whirling around a shrinking void. The planet was shredding itself apart from the inside out, becoming nothing. Finally, everything was sucked into the tiniest pinprick of matter...
Which then exploded outwards, breaking the debrie that had been the Combine overworld down to its most basic particles. The Combine had been completely and utterly obliterated.
And then the champions were back in the common room.
What happened in Gordon's home universe was... confusing. For the nomad who had ran Gordon's personal challenge had done much to change the outcome.
Normally, no one would've remembered what had happened. But they'd seen it. The whole thing had been displayed on the massive screens that Breen had installed around the various cities. And when the Combine overworld died...
They remembered. Even though time itself had changed, humanity had never been enslaved, every human remembered what had happened.
Alyx remembered, quite clearly, the crawl Gordon had made through the convection hallway.
She wanted to see him again, even if she had no idea how he had been there.
"Oh, dear. The toad, the monkey, and the dog have all screwed up."
