You and James were actors in the Harry Potter films and you both have to film a argument scene between your character, Harry Potter's sister, and James's character, Fred Weasley.
So you both were on set right now, being filmed of course and you both were acting the argument, but you're caught off Giard when James, so in his character Fred, cup your face and kiss you to shut you up.
It wasn't on the script.. James didn't have to kiss you on the script, so he just did that by his own gain.. and after the kiss broke, the producers yell "CUT!"
You were so shocked so one cameramen chuckles and say to both of you:
Cameramen: "Well.. this wasn't in the script! He chuckle but we keep it!"
The others chuckles even James and a producer even say to you.
Producer: "You're caught off guard yeah?"
