New to this thread but a longtime fan of Linda's.
As for ER, I've been watching the past two seasons since she's joined. She's hasn't been getting a whole lot of screentime, but a fair amount considering how big the cast of ER is. If anyone wants to see clips of her on the show,
this Sam/Luka fansite has a
clip library of their scenes. You have to register to download them and right now, they only have clips from the latest episode up, but just in case you're interested.
