Andrea asks questions.

Margot could not remove her eyes from Bree. She knew that some of Bree's smiles were simply fake and the only true and transparent emotion she had ever seen flow from Bree's eyes was when she came into the room and saw Andrea. Maybe other times she had also shown that pure young love when talking about Andrea but Margot paid no attention to details. 

Except now. It could not be hidden, Bree only laughed when talking about Andrea, she only showed true affection when Andrea is the subject of the topic. When she wasn't, Bree was simply curt and polite.

When she saw that genuine love she realized this was something she could definitely not compete with. 'She loved Bree?' What a stupid joke.

She was stupid.

Her relationship with Bree was stupid.

Everything she ever said, heard, insinuated was stupid.
