Ah, Black Mesa. Truly you and I, and all of our colleagues, were pushing the envelope of scientific endeavour to its very limit! Of course, we pushed it too far, hadn't we, Eli? Now the world is certainly a more vicious place than we had left it, and now our only hope, if the vortigaunts are to be believed, lies in the return of my previous subject of my mentorship, wherever he may be...
What's that, Eli? Yes, I'll look after Alyx for you, just don't venture too far from the camp site!
It's okay, my dear! Here, let's get you comfortable. Now, would you like to hear some more about your mother, Azian? You look exactly like her, even at 5 years old!
