I believe this preview is about that, we saw at the end of the last ep that Quinn basically kicked the MC out, so he could leave without anyone seeing him, in my opinion their relationship took one step forward and three steps back, and this angered the MC, Quinn is too complicated, they had an argument that made them take a step back in their relationship, and this conversation in this preview is to define the status of their relationship, if they will become something, or they will stop seeing each other.
In this preview Quinn is looking away, it's a conversation they need to have, but she wanted to avoid it.
