I agree, I think the final result will be Hillary and Devon but the only way to make drama from this is to have her hook up with Neil first. Simply because I don't see Neil going there AFTER Devon. If they do this storyline correctly, it could be very good.
The whole "I'm beginning to have feelings for you" line from Neil doesn't wash with me. While I think he's learned to trust and like the woman, I think he's just latching onto anything right now because Leslie shredded through his heart recently.
Honestly, I'd like it if it turned out that Leslie was blackmailed into marrying the doctor via Ian and this secret he told her in lawyer/client confidence. I'd love to find out Leslie married this guy to protect someone...Cane and Lily maybe? Neil himself? Tyler?
Whatever the issue is...I'd like to see several stories combined into one huge arc with Ian as the puppetmaster pulling the strings.
