Felicity had been seeing something weird on whatever scans of the city she was running. 'Slight seismic activity' she called it. More than that, it was coming closer and fast. Even more than that, it was heading straight towards them. And then it stopped. Right above them. And so Ollie went. And found Barry Allen dancing around like his feet were on... Okay, so his feet really were on fire. Or at least they were steaming.

"What in the hell is going on? Barry?"

Not that they were best friends or anything, but he'd expected at least a call before Barry made the trip here. Or during the trip here. Not to create...

"Wait, you were the source of the tremors?"
