I don't think mere goodbyes should count. The women do exchange a couple of lines earlier(And you first date was yesterday? The day before. Oh, The day before, Okay), but I don't think that's long enough to pass.
The only lines particularly between the two women that I caught was "It was so nice to meet you" from each. The rest seem to be between the couples in general.
I think this should be a 1.
I think it hardlyy counts.
