It was in the final moments of the episode that we realized something was very wrong in the grand scheme of the series.
The majority of “Mixed Signals” was relatively fun and silly as Team Flash adjusted to having Barry back after his time in the Speed Force.
He and Iris weren’t yet back on the same page, but we got to see some old school Flash-y shenanigans as Barry had some issues with the fancy features Cisco installed in his new Flash suit.
After locking metahuman Kilgore up in a cell that would deprive him of using his abilities, Barry and Joe asked how he got his powers despite being in Silicon Valley at the time of the particle accelerator incident.
