I think you need a beta. There is only one mistake that I caught, but there might be more. Here:

{Jet flinched as the microwave beeped, each tone causing a flashback. Post traumatic stress disorder they said. Caused by his hallucinations inside the machine.

Flynn’s back was still to Alan as he started speaking, watching the mugs go around inside the oven.

“So what makes you think it was real now?”

Jet looked up at the single incandescent bulb that lit the room, breathing in deeply through his nose, then slowly letting it out.}

I think you want to have Jet in there, as opposed to Alan. Other than that, good.
