Imagine losing someone you cared about, and everyone around you—with whom you previously got along okay, for the most part—is glad they’re gone. That’s what Vince went through when the BoBs rescued him late in the Lh'owon campaign; everything up until Durandal’s return was…very emotionally-taxing.
I’d like to think that, if he noticed (and in this case, he certainly did), Robert Blake would be a bit jarred by and maybe feel a little guilty over that, even if it didn’t change his opinion of Durandal.
(Note: Vince’s attire here is loosely based on what the SO wears in later chapter screens. His armour and jumpsuit were probably shredded beyond usefulness by this point)
