well, I'm pretty sure it was Mr. Dimitri Knight who Miss Kimberly was flirting with. And if my sight didn't deceive me, I'm pretty sure he was flirting back. ;)
Absolutely normal my dear, the older Knight is probably making up for the time he has been without someone, I think I never saw him with anyone again since he broke up with Rebecca.
Another guy that should move on from his ex-girlfriend, or maybe not, maybe we are all seeing this wrong and they all need to get back together. If we start thinking, Scott is still into Sofia, who has been getting messages to have sex with her bestie Rebecca, who has the same messages and is still angry with her ex Dimitri, the four together in a room would be something delicious to watch.
As for Kimberly, you all know she never caught my interest, always over Carter but clearly still thinking about her ex Ethan. Oh well, everyone needs an extra shoulder to lean on.
