These guys are dressed the same as the 2 guys you pushed off the roof outside. So if they're house guards then you dropped 2 Gralhund guards off a roof across the street.
Declan would also recognize they're dressed similar to Ustul Floxin, the guy who limped away after the explosion, and the same as the bodies who seemed to be associated with Floxin at the site of the blast.
I knew that guy was trouble.
