Theirs not really much to do but search, we have no clues at all and I'm guessing that Vlad would've Made the Vents big enough for a person to go through as a challenge, but made the vents towards the more secure and No-Go Areas Smaller.m and Vald could've left behind the map as a clue. 

Also theirs not really much to do, without crawling through vents all I can do is post "Tyrone searches the bathroom" "he finds nothing "tyrone goes to search the kitchen" Etc and its not exactly very interesting to do that over and over again.
