But they already knew that someone on the team betrayed them so that comment doesn't make sense as she would have been asking a question they already knew the answer to.

Quentin said that someone on the team betrayed them and Felicity says later "We do not know this isn't an evelyn sharp situation yet" this definately means that she is referring to Evelyn literally by implying that she is alive, they would know if she was dead or alive so she must be alive.
