You may think of Elanee as a neutral, being a druid and all, but she's actually quite a goody-two-shoes. Anything you do that's helpful or respectful of others (including especially natural critters and environs) will gain you influence. Also - obviously I hope - taking her side in any argument or agreeing with any of her suggestions will pile up the influence. As for the specific romance dialogs - she is hard to get and you'll have to dance around for awhile before it becomes clear she's hot for you. Dropping the subject may be the best you can hope for for a time until you advance your non-romance influence enough. I know you've got to get far into the game before she'll reveal why she's helping you. DON'T flirt with the other chicks around her, of course; but in one case, the best option might not seem that way at first (she'll say you seem to be paying a lot of attention to "the horned one" (I'm sure horny was the intent) and you should say something like "why not, she is a fiery little dev..." er, "beautiful woman;" after a bit more banter, if Elanee says you might have other options you haven't noticed yet, you're on the right track.
