"I've been up here more than once." Sai paused to listen for noise as they ascended the stairs. It was common for there to be something or someone guarding the main hallway, and it was doubtful that it would be something he could take on his own.

Hearing nothing, he continued to press forward.

"You should keep behind me." It was unnecessary advice, as he doubted Vlad was going to attempt to sprint past him up the stairs any time soon. All the same, it wouldn't hurt to take precautions.
