Contacts Trivia

There are a couple of strange things I notice in this episode. The first is near the beginning Danny, Chris and Jesse are walking down the street towards the school discussing "it's who you know not what you know". Suddenly Danny wanders off to the side of the street and greets a girl with long hair, giving her a huge hug and what looks like a kiss. Who is this girl? Does Danny have a new girlfriend? I thought at first it might be Nicole but the hug and kiss seem a little over the top for just friends and Jesse is standing right next to them

The second thing is after the party where Nicole sings another night Danny, Jesse and Chris are walking down the school corridor and a couple of times the camera looks up too high exposing that the corridor is just a set and doesn't really have a ceiling as we can see the soundstage.
