You can really feel the hate for Jackie Tyler flowing through your veins, and the subsequent calm after she's been burned without her knowledge, with this one. She's a fabulous disaster. She's tried to "intervene" in situations she's never remotely been a part of, tried to flirt with the Doctor (which was arguably the best let down ever when he declined her offer!) who, then again, was sort of completely romantically involved with Rose in the future, so, it makes it really weird. And she even got herself a new husband because of the Doctor, all the while hating him, which is preposterous! Now that is just selfish. And selfish people deserve hypothetical, but at times literal, burns... right?
