Honestly though, as pointless as some of her recent stints are they're pretty benign. None of them are nearly as terrible as her original return in the mid-2000s. It's sometimes hard to remember now, but Guza had her holding Port Charles and thousands of lives for ransom over the monkey virus. That was horribly OOC for Holly (who I have no profound fondness for, I like Emma but I was always an Anna/Finola stan) and that same creative team spent years after bumbling around trying to make up for it with goofy comedy con artist hijinks designed to lighten the character up again without really addressing it, and I'm not sure they ever did.
That being said, while I've always wanted Robert and Anna back together I know I am in the minority. And if it gets him away from Diane I am all for Robert and Holly reuniting yet again.
