Jordan's mum was very clever, if the edit is to be believed.
If some little trollop sat there armchair-psycho-analysing my son (who I know to struggle with mental health issues) and telling him what he needs to do to get better (OK she didn't say that specifically but it was implied) whilst trying to get me on her side, I would have told her to duck off to the far side of duck.
However, Jordan's mum can clearly see that Jordan values the relationship with Erica and in order to keep him onside and seeing her (mum) as a place of safety, she very clearly told Jordan what she thought was best without turning it against Erica. I don't know how to explain it as it wasn't what she said, but how she said it made me think she wasn't too impressed with Erica.
