The lesbian scene!

To those of you that have seen the film, may I ask, what did you think about the brief lesbian scene in the film between the lead actress Kirstine Carlstrand that played Virginia Hill and her Partner (Taimie Hannum), where that guy Dave Mulholland was watching? And did you in any way understand, was that scene just a fantasy of Mulholland's imagination while he was given that polygraph test, or was it his flashback to the memory that REALLY happened?

Yeah, I KNOW that this isn't the type of movie one watches for the plot (and I have similar related questions that I may address later on, but not in this thread), but I got kind of confused by that scene as it was never explained.

I mean, not once was it mentioned in the film that Virginia Hill was also bisexual. And I wonder why and how he got that other stripper (we've seen her also dance in the club) to get it on with her while he watched!

So was it just something he imagined in his head in order to help him beat the polygraph test or just something he remembered, and if that was the case, then how did his memory flashback as such help him beat the polygraph test after he got asked the question "Were you involved in a sexual relationship with Virginia Hill?"

What, on the other hand, did you think of the ACTUAL scene, was it nice?

Anyways, let's discuss, what was that lesbian scene all about, and was it real or just a fantasy of that guy's imagination to help him beat the polygraph test?
