You couldn't leave him. You just couldn't. Even if you barely knew him, you just knew that Luis was a good person, and you could tell that Leon knew that too, for the look on his eyes when you both saw Luis sitting after the meeting with that Krauser guy. You acted as quickly as you could to the situation, without neglecting the mission for which you were here in the first place, of course.

You separated from Leon. He went ahead to rescue Ashley, promising that he would constantly check if everything was okay over the radio, and you stayed with Luis, doing your best effort to save him from death. You did everything on your power: you used almost all of your remaining cures to treat his wound, staying only with a first aid spray for an emergency case. And oh that the emergency case came quickly.

The spaniard was unconscious, but at least he was breathing and stable. The advantage of Leon having gone ahead was that he had cleared the path quite a bit, so you didn't have much problem dragging Luis around. But, of course, he couldn't just kill all the things that were around the place. And those damn Novistadors things reproduced like cockroaches.

You're not sure about what happened. You were fighting the things, making your best to keep Luis safe from them. From one moment to the next, a Novistador bites your arm while you are trying to protect Luis from an imminent attack, leaving you weak, fainting once you kill the monsters.

You woke up, without knowing how much time passed, grunting softly. You were resting against a pillar of Salazar's castle, and your wound is bandaged with... a piece of fabric? You tried to stand up, but you're quickly stopped by a pair of gentle hands on your shoulders, followed by that familiar spaniard tone that you missed already. "Woah! Easy, amigo!"
