"We were about to go and look for you!", Brianna told Liz when she saw her returning to the bar.
Brianna and Mia exchanged quick glances when they saw Max one step behind Liz. They recognized him from the photo, but they can't say that. Talking about that photo is a taboo.
Mia and Brianna spoke about Liz and Max A LOT. They are aware that Max hurt Liz's feelings, but they believe that he didn't do it on purpose. After all, he is not the one who took the photo, posted it online, or made any inappropriate comments. Quite the opposite! Based on what Liz told them, he was a gentleman and he put in a lot of effort in wooing Liz.
