"Maybe I was just busy..." [ The only excuse that he can come up with. In actuality, a lot of it likely has to do with his lack of consideration to start writing any sooner. Not until after realizing that there's an actual plan in motion, and he needs to take the required steps to make it happen. ]

"This monster is too big to mount anywhere— it has its own torture chamber in the castle basement where it's all shackled up and I couldn't tell what the mural drawn on the wall before I went in really meant." [ See, he doesn't have the luxury of smart friends like Sypha or Alucard there to accompany him. Just his confused self and a lot of trial and error. He's spent days attempting to figure out simple mechanics, either from being lost or from being too initially unobservant. ]

"Tell Trevor not to do that, though. He's going to traumatize the taxidermist." [ He's frowning deeply, still combing through the pages about fighting Death itself. Explanations of the encounter. Eventually, though, he does come across a page that Other Him has dedicated to a drawing of the notorious monster, but his lack of artistic ability leaves much to be desired. The drawing is a asymmetrical, and the giant maggots look more like poop than anything else. ]

"Look, it's this." [ He can't tell he's bad at drawing, and he shows Alucard with a grim expression on his face. ]
