Imagine Barry forgetting something important and tries to make an excuse and cover it up.

"So Barry did you tell Cisco to make that banner for tonight" You asked Barry.

"Umm ya I did. Ya."

"Barry when did you tell him?"

Once the words left your mouth you felt a Gush of wind blow past you and just few seconds later Barry came back.

"3 seconds ago."

"Ughhh BARRY!"

"I'm sorry. Cisco said he can get it done in time so don't worry. In the mean time wanna get coffee so I can make it up to you?"
