Miami girl and Ariana’s reaction…

So doing a full rewatch and I can’t believe how stoic Ariana was able to be during the whole Miami girl situation. I would have lost it, and definitely not been able to put on an act. Whether I believed him or not, either way something inappropriate happened. Isn’t the start of a relationship supposed to be the best, most committed time in a relationship. Still boggles the mind for a few reasons. He must have come up with quite the sob story of how it all happened. Thoughts?
