Does anyone think Lea sort of has a crush on Cory?

I was just watching all the video diaries (again), and I was looking for signs and I thiiiiink she kind of acted like she has an eensy crush on Mr. Monteith. If no one else thinks so I'll be most relieved (Mark/Lea shipper here!!), but if so, it seems we have a real live 三角形 on our hands: Mark's totally in 愛 with Lea, Lea likes Cory, and Cory doesn't like anybody (I didn't get that vibe from him)! :P
What do あなた think?
