well, of course that’s impossible to know without knowing either of them personally, but there’s nothing to suggest they’re not still friends. as for heather’s views on brittana, she has given mixed opinions in the past but it’s hard to judge what she truly thinks, and i’m sure she’s happy to be part of such an important storyline and is proud of naya’s work.
this is all just the feeling i get in general but i’m not claiming to be any great font of knowledge regarding their relationship!
