Clone Wars Speculation: Lux, Ahsoka and that Secret Anakin/Ahsoka Scene

As we see the return of Lux to the Clone Wars series it has me pondering his relationship with Ahsoka Tano and some themes about Jedi and romantic attachment that TCW is playing with.

It was revealed at CVI that Matt Lanter (Anakin) and Ashley Eckstein (Ahsoka) recorded a session where all other cast members were taken out of the recording room.

This has me wondering, there are a number of possibilities about what this scene could be about.  To me the two strongest possibilities are based on relationships. To me this scene is likely either about Anakin-Padme or about Ahsoka-Lux.

I would not be surprised if we see in the 4th episode of the Onderon arc "Tipping Points" Lux die in battle and Ahsoka pushed towards the Dark Side.  Could she mimic Anakin's Sandpeople slaughter, except her fall to the darkness would result only in droids being slaughter, thus preserving the morality of the character in the viewers eyes.

Anakin sharing his own brush with the Dark Side with his padawan would be an intense and interesting scene.

I also think it would be interesting to explore attachment and loss with Ahsoka, because it looks like we are going to get something similar with Obi-Wan in terms of Satine this season.

The contrasts with how this experienced Jedi Master Obi-Wan and this young Jedi Padawan Ahsoka deal with attachment and loss are important counterpoints to Anakin's struggle with the issue.

Will Lux survive the rebellion on Onderon? We will have to watch and find out.
