Impulsive Excessive Disorder

This episode marks the beginning of Interlude II. "Bart, listen to me. Nobody is perfect. You are. That is not true. Yes it is. You knew when to come back here. You got the flash drive. You even helped Grandpa Joe and Grammy Cecile. You... Yeah, you're perfect. I'm a complete failure. No... No, you're not. I failed a lot too."

- Bart West-Allen and Nora West-Allen
