His likeness always like someone else

screaming

He does get long fine with Mina though he did have to be coaxed into actually interacting with her for longer than a few minutes at a time. Adam is very self-conscious and tends to hide when there are strangers around. Mina's kindness wins him over and he starts to open up to her a bit. Jonathan is a bit wary of the 8-foot tall super human made of corpses but he's polite at least. They occasionally make very strained small talk. At least twice Jonathan has done something Adam found mildly irritating and he thought "Ah...that's where Quincey gets it." It's one of those relationships where neither of them is really doing anything wrong but they have such opposite vibes that there's no hope of them ever being real friends. Jonathan might try to start a convo, "Read anything interesting lately?" Adam will light up for just a minute and start yapping about Caliban from Shakespeare's "The Tempest" and Jonathan's smile will freeze and his eyes will start to go glassy when he realizes that Mr. Frankenstein is about to inflict a long and emotionally fraught monologue on him. Arthur Holmwood is at least partly funding the crew and providing his support in their efforts to kill Dracula so Adam has no beef with him but as nice as Arthur is Adam tends to be avoidant. Adam gets along well with Selma, who is the late Quincey Morris's niece, he'd probably have gotten on similarly with Quincey provided Quincey didn't do anything foolish like remark on Adam's appearance or react fearfully or aggressively. I feel like Van Helsing would have made him uncomfortable. He'd have asked too many questions for Adam's liking and Adam would always be a little afraid that Van Helsing might decide Adam is some kind of abomination that needs to be destroyed like the vampires do. Jack Seward-Adam has met Seward. He despises him. Seward reminds him a little bit of Victor and finding out about his dehumanizing treatment of Renfield while Renfield was his patient didn't help. Seward isn't terribly fond of Adam either and tends to be anxious around him.

There is of course a "Pay no attention to that bat behind the curtain!" moment

aka the blonde vampire that tried to eat Jonathan Harker on May 16th

sorry I know you meant adapted but the concept of Dracula being adopted is SO fucking funny to me

NONE OF YOU CAN PLAY WITH HIM ANYMORE

If I am wrong, Stoker's ghost can come yell at me, but I feel like even if Count Dracula only had the most tenuous connection to either Attila or the Draculesti, he'd still brag about it insufferably. Like that person you know who's three percent Irish according to AncestryDNA and still makes it their entire personality.
