This has got to be one of the most ridiculous things I've ever seen on a soap. And that's saying a lot. It's official. The writers just don't give a damn anymore. I hope Liz Gillies has the acting chops to pull this off because if she doesn't, then this is going to put a permanent black stain on her career and nobody who is worth their salt will ever hire her for anything worthwhile ever again.
Honestly, I'm half-expecting Adam to probably end up raping Fallon at some point and knock her up with his baby. Then Liam can show up again to not only be verbally and emotionally abused by Fallon again but he can also pose as the baby daddy so that the Carringtons' public reputation doesn't get permanently ruined. Then Fallon can debate on whether or not she wants an abortion, (which she almost certainly will), and Liam will beg and plead with Fallon to not go through with the abortion because he has become attached to the baby for some reason but she goes through with it anyway, because to hell with him and everyone else. This actually wouldn't surprise me if they went this route because so many insane things have happened on this show that part of me wonders exactly what haven't they done yet.
Seriously, if I were Liam, I would run and never look back. As long as Fallon continues to manipulate and use Liam for her own selfish and narcissistic purposes, they will never, never, ever have any sort of a healthy relationship, (not like they even had a chance in hell to begin with, but I digress). Probably the only reason why he tolerates her crap so much is because that's the type of behavior he's used to from his own mother growing up.
Speaking of Liam's mom, I'm at the point where I'm actually hoping that she does something to destroy the relationship for good so that neither of them will have anything to do with the other again. If this were a better written show, maybe they can do a storyline where Fallon is abusive towards Liam and Liam keeps mum because he's afraid that everyone will laugh and mock him all because he's a guy and guys are supposed to be able to defend themselves from women. If done right a domestic violence storyline involving a male victim could probably be one of the most original and interesting things this show has ever done, but maybe it's for the best they don't go this route because just like everything else they'll screw that up too if given the chance.
