The surrounding tunnel gave an immense shutter, and outside, the shark could hear- even feel- crumbling of rocks from outside the underpass. Bruce braced himself, instinctually moving closer to the other as the environment around him moved. Then all of a sudden, all the rumbling and earthquake like motions came to an abrupt halt. 

A beat passed, and Bruce arched a brow. “Did it work?”

The Repairman fell into the panel with an “oof!” as the quake started. Miraculously, his inky form did not hit any of the outlets.

He clambered out once the motion stopped, feeling slightly dazed. After a moment, he looked around, then sighed.

“I guess not. I… guess I could check–”

Click. The incandescent lights suddenly turned on.

“Gah!” he exclaimed, shielding his eyes. “I guess it did.”

When he could see again, the Repairman noticed the doors were still closed. However, a smaller panel on one of the walls was being opened, revealing a robotic hand.

He began to approach it, hoping it would lead to a way out.
