WILL, EMMA AND EMMA'S NEW BOYFRIEND CARL (JOHN STAMOS)

Jayma Mays on Whether She Has Kissed John Stamos: "No." Is she looking forward to it? "Yes. I can't stop smiling when people say his name. It's very inappropriate...With a dentist like that, you kind of want to eat a lot of sugar."

Matthew Morrison on Who's Better-Looking: "I think John will win that battle. But if we have a dance-off, I might win that one. We're both fighting over Emma this season. I'm so excited to have him on the show. He's a buddy of mine and I can't wait." On who would win a hygiene-off: "Stamos, absolutely. He's playing a dentist!"

Executive Producer Brad Falchuk: "I think [Will and Emma's] relationship really grew over the first season and so much of it was dependent on Will not being available. And I think that's what was kind of so interesting about those two characters is like 'Hmmm, we kind of like each other but we don't have to commit to each other because you're not available.' And suddenly Will became available and it became much more complicated, and now she's not available, and so now it's even more complicated. So I think they'll explore all aspects of their relationship where these two people clearly care about each other, will maybe end up in each other's lives, but can't seem to kind of get it together."
