Yeah I've had an issue with no photo drops from the friends as well. Then this morning I had a thought on that, where it's possible they were there and nothing happened. (Even though it's less likely than the "obvious ") Let's say all the friends are married or in serious relationships. They believe that nothing went on and drop those pics showing they were there. But then it's 100% confirmed that Vrabel and Russini are indeed having an affair, but perhaps the friends truly didn't know about it.
It doesn't matter, they instantly look bad to their significant others. They're helping their friends cover up an affair. That's not easy to come back from.
