You are walking along the corridor of a military base at night, why at night?, unfortunately you wanted to drink coffee, and you went to get it, while walking you heard strange sounds from the ceiling near the ventilation, raising your head and shining a flashlight there (because it was dark), you notice Roach holding onto the ventilation and hanging on the ceiling, with a loaf of bread in his mouth, Roach carefully looked in your direction, and then said.

-heey... hello Lieutenant..

He said this quietly and pulled the loaf out of his mouth, you looked at him in surprise, no ..of course you knew that Roach likes to sit in strange places and all that, but to climb on the ceiling!..it was a shock for you.
