Jecht was really impressed by Lenne in their battle to free Yuna, that's for sure. Though he doesn't know her connection to Zanarkand yet, rest assued when / if he finds out, he's gonna be all over bonding with her about it!

When it comes to young women, he immediately seems to shift into this "HEY IF YOU NEED ANYTHING, JUST CALL ON ME" sort of attitude. Probably from his playboy days (it's hard being the best, y'know, heh) so expect him to be on the protective side in the future!
