At the end of Half-Life 2, Gordon Freeman has successfully destroyed the Citadel, the main base of operations for The Combine in City 17. The reactor has blown up, about to swallow Alyx and Gordon in the fireball. Just as they are about to perish, G-Man freezes time and abducts them.
Time, Dr. Freeman? Is it really that... time again? It seems as if you only just arrived. You've done a great deal in a small time-span. You've done so well, in fact, that I've received some interesting offers for your services.

(The world around Gordon fades away)

In the meantime... this is where I get off.
