Last time on The Flash, we got a dose of nostalgia as Barry (Grant Gustin) went back in time to get evil Dr. Wells aka Eobard Thawne (Tom Cavanagh) to help him run faster. We got to see Eddie (Rick Cosnett) once more, and Barry got Eddie to make a love video for future Iris (Candace Patton), who had been having a hard time moving on. Past Wells figured it out but agreed to help future Barry anyway. Barry mucked it up even more so that Cisco and Caitlin (Carlos Valdes and Danielle Panabaker) found out too. His only saving grace was that he did not reveal what was in store for Thawne. We don’t know the full consequences of his time traveling actions, only that when he got back, Hartley Rathaway (Andy Mientus) was now on Team Flash.

Spoilers below.
