Erm, we didn't do a whole lot of talking at all, in point of fact.

[Iris doesn't do embarrassed. But, while she hasn't necessarily reached a conclusion as to who Tig evokes for Allison, the dynamic of that friendship's very plain.]

...but it's not 'ard to join the dots. Allison. Listen to me. It doesn't matter who you remind each other of, all right? Tiggy's not very trusting, 'e's just got landed with a warden I don't think 'e's going to find easy to trust either, and 'e needs people badly. Don't start thinking you're not good for 'im just 'cause of what you're getting out of it. 'E's going to need you too much for that.

[And vice versa, if Iris is any judge; but she doesn't say that aloud.]
