Corey and Sean's Dilemma

I did definitely notice shadows in this episode because when Corey actually gets up to Topanga where he stands, his face is totally shadowing my face. And I wanted to be like, adjust this blocking or fix the light. But it happens a couple times where it's just bad, bad shadows. So also Corey and Topanga both have their sleeves rolled up. Everybody's looking very 50s. Roll a smoke in there. Topanga just casually mentioned that they have all the same classes together again. They had them together last year as well. The relationship must change accordingly. Just a great line and very funny. But why does the bell ring again?
