It's a complete 180 from Pearl's attitude less than a week ago when she first walked into Deep Black Vinyl.
Well that's the point really. We saw Miriam arrive in this very place, apparently someone very much in control of herself, and someone very unimpressed by a
very similar situation (right down to the only other non-participant awkwardly offering her coffee - and she wouldn't even drink that). And then we saw her again (eventually), in private, being affected by something. And then she took (I suppose) a conscious decision to succumb to the charms and innuendo (respectively) of Réka and Weston. And now here we are again in the same public place, with shenanigans on the go, and here she is being fingered by Réka. And she's too horny to take the offer of a return to propriety. She even accepted the coffee this time.
I mean: "Someone's done something to my mother." Well maybe you should take a look in that ornate mirror of yours, sister.
