I know I wouldn't want Miriam blaming me for something like that.
That would be quite a plot twist.
The closest I can remember is him being frustrated that a shopping run with "two things on the list" led to a confrontation that resulted in more temporary guests.
Are you sure you're not thinking of Jayson being angry with Chanice in that episode of
Oh No You Didn't! - you know, the one where they found out Amberlene had been sleeping with Quinine?
Erin invited Miriam to come and see her tonight. I think her intention was to teach Miriam some things - presumably of a magical nature. (Maybe she'll come to regret that.) She could be lying about what they did, but if she has a guilty secret she doesn't want Miriam to know about, she might have done better to avoid her rather than arrange an unnecessary further meeting. At the moment I'm inclined to think that this is the reveal for what went on with the pendant.
