I've read the Hayeses talking about Doug and then Julie's solo returns and to this day I don't understand what that was about. I am not well-versed enough in Days BTS lore to have any insight. It just doesn't make any sense to me why they'd bring them back separately.
I think RKK was an exceptional recast at the time. I remember him being very popular, but maybe that's me imagining things as a kid who was horny for him at the time lol. I was shocked when he disappeared and this hick I'd never seen before (Peter Reckell!) showed up! But of course we know now there were extenuating circumstances BTS, namely RKK being a serial creep.
I don't recall the details of what happened with Crystal Chappell or which came first, her being pushed out by the show?/JER? or her always being a drama magnet and choosing to flounce?
I remember seeing Tracy Middendorf's debut episode on WOST years ago and really liking it despite having grown up with the immortal Christie Clark. But I have a fondness for Tracy from Wes Craven's New Nightmare.
