Jennifer watched as Jeff looked right at her, then just... continued looking, as if nothing was wrong. Jennifer was confused momentarily, before quickly realizing, "Wait, can he not see me?"
Jeff finished his scan of the room, seeing nobody there. He was confused for a moment, looking back at the Chronivac. "How did I get back here?" He asked, trying to make sense of his memories - Memories of the original timeline where he transformed with Alan, and one where Alan didn't exist. But, lacking Jennifer's memories, he didn't know she was the culprit. "Wasn't I just outside...?"
He looked at the date on the computer, seeing it was still Friday. "So it didn't wear off on its own..." He observed, though after processing his altered memories, realized, "Wait, did Alan not turn back?" He opened up his and Alan- Felicity's profiles, even more confused when he saw that his timer was manually reverted, and that Felicity's was set to permanent. "Did someone tamper with the Chronivac?"
Jennifer couldn't help but giggle, watching the boy's confusion. "Even I figured that out faster than him!" She went to walk forward, but did the ghost equivalent of stumbling, forgetting she was flying. "Ah! That'll take some time to get used to."
She did her best to maneuver to the ground, where she managed to stand, switching to a method of movement she's more accustomed to: Walking. And so, she walked over to the boy, watching as he tried to figure out how to check the logs and see who might've done it.
