[ns] Looking for a specific episode/Teen Talk

Hello! I'm relatively sure what I'm remembering was from a Teen Talk, but it might also have been a regular episode during the Teen Fact portion?

There was a somewhat recent episode where Will was talking about Henry and Normal and mentioned some writing advice he'd heard about finding a contradiction within the character. I thought it was really interesting but of course I forgot to note down where the advice came from and now I can't remember what episode it was. Can anyone point me in the right direction so I can relisten? Thank you!
