Prompt: Back to Aperture! Chell got hit by pieces of falling debris and is now bleeding. Wheatley's never seen a human bleed before.

Chell ran towards the next room, feeling the spring on the long fall boots as she kept moving towards her destination. It was confusing to go through the walls between tests, and a room was just ahead on the catwalk. On a management rail to her right, Wheatley was clinging on the pole for dear life, chittering away to distract himself.

Suddenly, the ceiling caved in. Chell barely retracted her arms in time, in order to save them from being broken, or worse.

When the dust cleared, Wheatley jumped off his rail to check how she was doing.

"Oh gosh! Luv, are you okay?"

Chell gave him a blank stare, before looking down at her arms. One large, nasty cut was forming on her bare arm, and Wheatley was staring in disbelief.

She began to tilt her head to one side, a way of asking what was wrong, but then Wheatley's face began to change. The scene before him was clicking together in his head.

"You're… you're bleeding, aren't you? That's not good! Ahhh! Don't you silly humans run on that stuff or something? Keep it inside your body!"

Chell gave him a look, before tuning out his voice so that it was akin to white noise buzzing in the back of her ear.

Taking a pause to analyze the gap and the amount of momentum and jump she would need to cross, Chell tore off a part of her white tank top, revealing the blue underneath, and began to wind it tightly around her arm. Wheatley watched curiously as she did this, going silent.

When she finished, held out the arm to him, as if to say See? No more blood.

"Oh. Well that's all right now, isn't it? See here, I was beginning to think, and mind you, this might sound hilarious – I was beginning to think you were almost invincible! Never got hurt, you did."

Chell smiled to herself, knowing that this was his way of showing he cared – unstoppable ramblings. However, instead of listening, she decided to keep going, backing up and successfully jumping over the gap that was now present in the catwalk. Wheatley swung onto his rail, riding after her.

Going through the door and hearing the automated voice of the Announcer give the instructions of this destroyed test room, Chell took another pause to look around and figure out the order of events that needed to happen in this testing room.

Wheatley watched as she ran forward, perfectly tipping into a floor portal so she could find herself on a high up ledge.

Wheatley thought that bleeding bit had been mighty unpleasant. Humans could just get this little cut and bam! It was like their entire inner systems started falling out!

However, she brushed it off like it was nothing. What a spectacular woman she was.

…But what if she had been two steps closer to the door when the debris fell? What then? She got hurt? And she was still a human. A very capable one, but…

…If she could get hurt, couldn't she also be killed?

…Wheatley didn't want to think about that.
