Unsolvable

What are you doing this weekend?

Oh, opposite of the Berkshires. Workshires. Working. Whole weekend. Fighting crime.

Jake yawned hugely, scrubbing at his eyes. He was tired. So tired. He'd just rest his head on the table for a few seconds...

"Why do you want to solve this so badly?" Holt stood in the doorway, frowning curiously at the young detective.

"To prove to Santiago that I can", he said stubbornly, snapping his head up. "Were probably going to start another bet. I'm just going to get some coffee-"

"You haven't slept". Holt's voice seemed slightly softer (although his sleep deprived mind could be imagining things). "You aren't going to be any use to anyone like this".

Jake stepped past Holt, making a beeline for the coffee machine.

"I'm going to get some coffee and keep going", he said again. "And I'm going to show Santiago that I'm a better detective than Teddy Wells".

His voice was soft, and Holt almost didn't catch it.

"Santiago respects you", he said, and Jake took a long sip of his coffee.

"I just want to prove to everyone that I can solve this. To win the new bet".

Holt sighed.

He didn't understand Jacob Peralta.
