"We'll meet you back in Caitlin's lab," Barry calls after Cisco.

Turning to Yamato, Barry rubs his hands together as he considers the situation.

"So that narrows it down to the Infection or it getting excited about a fight." And Taichi definitely wasn't here so...

Glancing over his shoulder in the direction Cisco and Caitlin left, Barry then looks back at Yamato and asks, "Do you think it-- maybe, thought I was trying to hurt you, again? Or was a danger to it?"

Yamato had given his Crest to Barry to hang onto, maybe it took exception to that after what happened in Milliways.
