The "was not alone" part of the Dark Lantern thing doesn't mean more than one individual visited Christos, rather that he was visited by a group. We know lycans attack in groups and that the Golem protected someone from the lycan attack. Now, Golem is now an undead and Christos is the Revenant, a valuable asset that just confirmed the identity of the Werehyena and got him killed. It would be safe to assume the Golem protected Christos, he was visited, yet they weren't able to kill him. jdthebud is part of the list, night was a codeword and four of the people on the list are/were confirmed lycans. We weren't expecting all of the people on the list to be lycans, but it is safe to assume now that most, if not all (because wizardman11 is dead, RIP), people on the list are lycans.
Everything points to jdthebud being a lycan.
