After being sent out of the house by Bree in order to have a forced conversation, Sophia and Lucy simply stared at each other in awkwardness. But when Lucy's eyes would meet Sophia's, the latter would immediately look away from her, darting her eyes noticeably away, to the beige painted walls or to the uninterrupted staircase.
The silence and position the two of them were thrown in abruptly was a little too weird for them. But whether they liked it or not, they had to converse with each other as they could not go back inside, reasons being that Bree obviously had something to talk to Andrea about.
Lucy was almost finding it nerve wracking that because Bree wanted to spend time with Andrea she simply threw the both of them out in the guise of having a conversation.
