We were investigating Bren's (coterie-mate tzmiscie) missing touchstone, Haley's, home for leads on her, and Willow noticed a bullethole w/ blood spattered near it on the wall! She had inigo cut it out w/ his knife so they could give it to Lovelace later because he has Blood Sorcery!

....Normally A Taste For Blood wouldn't work with old dried blood but uhhhh Love rolled 12 successes on a critical win so he got a taste of it! And determined it was mortal with a blood potency...aaaand burned.

After Love spit it out because it burned, Inigo smelled it like a freak with counter inquisition and determined that burning sensation was true faith lmao. Also 1000% confident it was a gutierrez because he knows they've got Revenant blood in their line because of Darios.
