Personally, I think it would help the story if Sophia goes straight from the concert to the event with Cathy, Liam, and Andy. If she goes home and changes, I think the story loses some momentum. Instead, let her go straight to Cathy and Andy's apartment, a little drunk and dressed a little inappropriately; but not so much that it's a problem but enough to cause some tension. This game needs some stakes, and a slightly intoxicated and sexy Sophia could be the impetus for launching the next phase of the Cathy/Andy/Liam/Sophia storyline. If L&P's plan for Cathy and Andy is to make them potential LIs, and perhaps swingers, then let's start moving down that road. Let's not reset Sophia back to zero, sober and dressed conservatively, because that kills and momentum in the story. Let her show up at the apartment under the influence of whatever happens at the concert.
