continuity editing practical

we will be filming a short encounter between two characters, including a dialogue.
We will use outside the canteen for the establishing shot. with a back view of the character heading towards the door. Then after the close up and match on action, the rest of the scene will be filmed at a table in the canteen.

Here is our script:

C1: (slightly angry) Where have you been?!
C2: (panting)  Just escaped from the gym.. the instructor was gonna kill me! All those press ups -.-
C1:  (smug) Ouch and all while I've been eating chips!
C2: You'll be jealous when I'm hench! ;)
C1: Hmm I guess i shouldn't tempt you with any leftover chips then should I? (slides packet towards them)
C2: ahhh alright then!! (eats chip)
