Oh my! This is brilliant. I'm not seeing any anti-Meg in this, even if she is jealous. I mean, what's not to be jealous over? The pairing is definitely worth being jealous over.
As for Meg, so she's a little jealous. She is also still the amazing strong, competent, and beautiful woman that she is on the show. This just showcases her non-Mountie human side that we just don't get to see enough of.
