Looks like whoever Wednesday freed from Willow Hill has white roses on her dress...
Theory time:
So according to the credits in some languages, a certain Françoise is named in the character list, so it's most likely Tyler's mother, plus it would be odd that Fester doesn't recognize Ophelia
In Wednesday's vision, there are crows? ravens? but no crow with red mark, so these birds are not representing Judi's birds Edit: turns out in Xavier's painting, we do see the marked crow holding the white rose on the tombstone, so maybe they didn't bother showing us this crow well in the vision, so I don't really know what to think of it here, but this twitter thread is interesting
Apparently there were only 6 patients in LOIS (including 'Françoise'), so it seems Ophelia is not there (anymore?) maybe she got away at some point, or she died there
Ophelia might actually be the new guide for Wednesday, but considering what happened to her, her way to guide may be overly dramatic and much more cryptic that what Goody would do
The crow in the vision is holding a white rose, and drops it on Enid's tombstone, which breaks the rose with a porcelain sound?
So if it's Tyler's mother that just got released, she must be particularly unstable, and she is a Hyde which is one of the most dangerous outcasts
That been said I would be surprised if the major threat is once again a Hyde, feels too close to season 1, but maybe the twist is Françoise's master...
Also Slurp knew Augustus and is the one who killed the most people so far, I wonder how he'll be once he's fully 'healed', principal Dort is shady and working for someone, and I wonder if Bianca's sidequest with her mom will play something into the main plot, and Bruno is likely blackmailed by Agnes so he probably has something to hide, and Capri is one nervous werewolf so I wonder if she went through similar issues to Enid with her werewolf powers
