For what I feel:
Axel is a Master. Lena was his slave in there previous relationship (Necklace).
Now I'm sure that M. Seymour is a even bigger Master than Axel. So the submission path for Lena will be embodied by the couple Sith/Aprentice : Seymour/Axel. It will bring her "back" down the submission.
Wade would have to change attitude drastically if he hope to seduce Lena.
Stan will be a sextoy at the most.
Louise is too immature to become a strong partener for Lena.
Jeremy will stay the butterfly he is and try to fuck everything that catch his eye.
If Mike quit his girl friend he has a good chance to capture her.
Ed will be the old fuck.
Perry = NO CHANCE
Cindy could become something but it is reallly far away, as they just met once and the options where neutral at best.
Best possible relations in the future other the Ian:
1- Holly
2- Ivy, the long time friend that can become more
4- Emma
5- Mike (if he quit his GF)
And of course I let the doush in the bin.
