[The bad news is that I was unable to find why the Fly went. The entire first floor of their base is just rigged to explode, so he must be on the second floor. The problem is that there were no openings for me to search the second floor.]
[The good news is that their building is directly connected to the neighboring buildings. Which did not have as high of security measurements. I checked the two buildings on either side of their base and the top floor of their base had passages that lead to the second floors of the neighboring restaurants. It seems that all of these buildings' second floors are connected to each other. This entire side of the block. Luckily, I was able to search all of them and have narrowed it down to two buildings.] Leona explained.
[I can feel a 'but' coming.] Havok said.
[But the two presences that I felt were at opposite ends of the street on the second floors of the buildings.]
