Marguerite and Roxton are not at all compatible in this episode. If there had been more episodes like The Chosen One, we probably wouldn't have been rooting them on as a couple. In the treehouse, it was a sad episode watching Veronica suffer through Ned's alien possession. That was extremely creepy and I did not appreciate the strange hussy making herself at home in the treehouse. I did enjoy Summerlee's attempts to set Malone back on track and Challenger's compassion.
I think they were compatible in The Chosen One
. Roxton was reliving his relationship with his brother, William, and Marguerite knew it. She was also pissed at the kid, Gideon, for nearly getting her killed by Apemen, when Roxton and she had told him to just leave them be. This transferred over to her dealing with Roxton because she was feeling left out. You know how she likes (and sometimes doesn't because he can be so prying when it comes to her past) his attention, even if she doesn't always let on she does.
That and she didn't trust the kid, at all. I mean who would considering that he nearly got her killed. I know I wouldn't trust him. Impudent little snot! How dare he not listen to Marguerite?!
Yeah that whole "help me save my race" thing between Malone and that woman was a bit creepy wasn't it? Honestly, I really disliked how the Veronica/Malone relationship was handled. If they had started out with them only remaining friends I would have been okay with it. OR if they had hooked them up I would have loved it. But they flipfloped with that relationship. It got annoying, for me, after awhile. THEN when they were finally looking like they would get their relationship on track...well we all know what happened at the end of S3.
