Headscratchers / The Solve-It Squad Returns!

• Were Keith and Gwen ever romantic? The evidence for is that Gwen said she was the star of someone else's play in the opening and pointed to Keith. Keith also seems to believe that Gwen is her. At the same time, he said "I do what I like and I like Gwen" and that's different from doing Gwen. The group also replied with how inappropriate it was, as if they weren't a couple. Later, Gwen says "you and I will never happen" but that's also vague because it's difficult to know if she means again or once.
