You give Logan the timer.

Logan takes the timer from you and goes back to work.

"How much longer is this gonna take?"

"Yes, we don't want to miss our window of opportunity."

"Keep your pants on," Logan calls from across the lab. "I'm almost finished."

"Take it easy guys," you say. "We'll make it."

And so you wait. And wait. And the next time you call for Logan, she has disappeared.

You run outside the lab, but all you see is your vortex, closing without you, and Logan's unusable timer lying on the ground. She has double-crossed you again, and now you're stranded.

The End

Oooh! Give me another chance. I think I know what to do now.
This blows. Take me back to Earth Prime.
