On possible theories, I have a feeling Mike's gf is Gillian. In ch 9 Mike tells Lena he and his gf live in the outskirts of town.
In ch 5 Ian tells Alison Gillian moved to the outskirts of town to study or something. Maybe that's where she met Mike and eventually left Ian because of this.
I see no other reason why Eva would add this piece of dialogue.
