I literally JUST watched that scene! It was good. Adrienne has been great!
I have a slightly different perspective on the storyline, though (I know, you're all shocked). As Adrienne was yelling at Will and Will was telling her what was going on, I was thinking - you know, if anyone should understand how something like this could happen, it would be Adrienne.
I am NOT defending Will. I am NOT defending Adrienne. I am NOT defending Justin. But I am saying that I saw a parallel that ended differently. Will and Sonny were "having problems" and "drifting apart". They didn't really talk about it. Will allowed a weak link to become broken, and that's his fault.
Adrienne and Justin are "having problems" and "drifting apart". They aren't really talking about it. Adrienne is possibly jumping to conclusions about what's going on. (I would be coming to the same conclusions, for the record!) She allowed a weak link to become weaker by kissing Lucas, and continuing to seek out his company. That isn't the same thing as actually committing adultery, but it is the wrong thing and isn't healthy for her relationship with Justin. (Also keep in mind that I'm just watching Monday's show, so I'm obviously behind and other stuff has undoubtedly happened.) So in that regard, if anyone could understand how it could happen, it would be Adrienne. I would like to see her admit that - she can still be rightfully angry at Will (and should be) for what he did.
I am doubtful that this would actually happen, but I would like to think that if someone, especially Adrienne, at empathized with Will (not that he deserves it), he might turn that corner and be able to own what he did instead of constantly trying to defend himself. He would see that it isn't something that you can defend, and that while it was a terrible "mistake"... a terrible and stupid decision on his part... the only way he might get through this with Sonny is to get over defending himself.
If he keeps this up, it will backfire. Adrienne should realize this, too, because she isn't too far off from where Will is. I know she's angry - and she should be - at both Will and Justin, but I think she was taking much of her anger at Justin out on Will. The stories are related... I would like to see Adrienne be a mother figure (yes, even to Will) and see the parallels, back up a bit to do the hard thing and hear Justin, and do the hard thing and try to use her experience to steer Will in a better direction. She only needs to think of Sonny to be able to do this... the sooner Will fixes himself, the better it will be for Sonny - regardless where their marriage ends up after the dust settles. A desperate Will means an unhappy Sonny - married or not.
Wouldn't that be a surprise - to have a character on a soap do something unexpected and not out of passion - even if it is deserved? I know, I know... it will never happen.
(I also know it has happened before... I just can't think of an instance off the top of my head. Well, one, but it isn't worth mentioning. Haha...)
