DO NOT READ IF YOU HAVEN'T SEEN THIS WEEK'S EPISODE AND POSSIBLE SPOILERS FOR NEXT WEEKS:

If you were wondering if Barry's trip to the past would have lasting effects on the timeline, you sir are correct. Not only does Cisco live, but apparently will be getting a love interest, or is being played by Captain Cold's sister. In other news, I feel sorry for the people who just saw this on the social media sites that haven't seen last weeks episodes and just got is kinda spoiled for them.
