Alternative Repulsion Gel test
Chell stepped through the door. This test had a small amount of repulsion gel falling. A slanted panel was beside it.
"I'm telling 'em, keep your pants on." The prerecorded message startled her. "Ok, this next test may contain trace amounts of time travel." Chell ignored it. There was no chance that they were still working on time travel after all the years she had been in cryo-sleep.
She shot portal under the gel then one on the panel. Then she began searching for somewhere that she could jump off of to get enough momentum to fling onto the gel on the wall. That was when she saw a person sitting on the catwalk. You wouldn't believe how quickly she portaled up there.
Chell stared at the human who was wearing the exact same thing as her. The girl turned around showing Chell herself. Everything faded away into time.
Microsoft Word says portaled isn't a word. Apparently it hasn't come in contact with someone who loves Portal.
