They've sent some rude replies back today.

I mentioned that [my ex's new Trans name] isn't back and if this concerns the tenancy, we should wait for her, Tuesday.
They said that her name is not on the tenancy agreement, so she doesn't matter (Paraphrasing only a tiny bit).
I realized just then I half-outed my ex as trans, since they only know her by her dead name. What a weird and awkward situation. She's not mad and I'm okay to clear things up.

So basically.
As I suspected, one of their problems is they think I'm subletting (Because [new name] is not whom the agreement is with *eyeroll*) , even after I *explained* in English why it's [New name] not [deadname]. ..oh well.

There's also "Other things", still nice and vague. They don't want to leave a paper trail of what they said, for sure.
Guessing one of these is going to be Daisy since that was also not in the original agreement, but if they say they want her gone, they've got a very pissed off dog dad on their hands.
I'll find out more when they show up around 10:30 tomorrow.

As a note, landlords are required to warn tenants 24 hours in advance of when they want to drop by so someone can make accommodations to be home. *I* offered the date tomorrow, *they* didn't ask me about anything, so if they want to come in, I'm not going to let them. Pissed off at the reply style being used today and the wanky vaguery to be honest.
