ranagrande and Taiga are the only two who have had an interaction with the zombie. Next to this we have Praziquantel and ? who did see him, but did not have a conversation.

Can any of you four explain to me what the difference is in the interaction? I'm trying to see whether I can understand whether the same thing happened to all of you, or that something else happened to rana and Taiga, than to Praz and ?.

Praziquantel said "not visited by him, just saw him", ? also mentioned "Not visited but I saw him", but he appended with "So yes I guess".
Praz and ?:
- the zombie apparently didn't say anything TO you, but did he mutter? Did he say anything (mumbling, screaming, demanding, whispering)? Did he pass you outside the window, through the hallways? Was he in your room?
- ?, having read the other three, are you now saying you were or were not "visited" by him?

ranagrande: "(...) I was visited by the strange wanderer looking for brains."
Taiga: "I also got visited by this zombie-muttering vagrant. (...) he also carried a bottle of wine (...)."

rana and Taiga:
- was it truly interaction, were you visited in your room, or would you say he more noticed you, saw you had no brains to offer (whatever that implies ) and moved away?
- did he say anything? Or was it truly a case of "Brains. BRAAINS. BraaAAAAIIIINS." type zombie-behaviour? Or was it in line with what the opening says: "demanding brains" and no specifics on the conversation.

(Please note: I don't want nor encourage you to mod-quote, or give away more than you feel comfortable with. I'm merely listing things that may help us determine the nature of the zombie.)

The others (except for Stephen, whom we haven't heard from for a while) did not have anything to do with the zombie. (Did I count correctly?) Not much to correlate this with, though. Only possibility I could think about was the event yesterday, but that doesn't correlate at all. Did you have a next step in mind rana?

Plus I keep having trouble wrapping my head around why you are all so certain it's the same guy. Is it the ladle? The bottle of wine? And what would he do with it anyway? Is he a cook, trying to make brain stew, with a nice chianti?

And of course: what does it have to do with anything? You all don't seem to feel this has anything to do with the Undead, but then what? Red herring salad? In that case: drop this line of inquiry and propose something useful.
