For @prentiss-theorem bingo (I hope it makes sense, I'm not very good at writing)
Emily only eating chocolate and candies but after a hard case she's craving something else , so when everyone else are sleeping on the jet she goes to the kitchen and takes one pack of JJ's Cheetos, but then JJ wakes up hearing noise and goes to the kitchen to see where the noise is coming from. And she's seeing Emily eating her Cheetos
JJ: What are you eating ??
E: You wouldn't by chance believe me if I say this is not what it looks like
JJ: Why don't you tell and we'll see
E: Uhm .. you see ... it's ....
JJ: Is that ... Are you eating my Cheetos ??
E: Uh no...??
JJ: Emily !!! This was my last one
E: Sorry !! I'll buy you a dozen !! Look you can have the rest of them , I didn't eat much. It's just this case was very hard and I didn't want to eat chocolate again and they were there and you know I don't eat this stuff butI have seen the face you make when you eat them so I guessed the were good , so I gave them a chance . Sorry again
JJ: Oh Emily it's ok I understand
And then JJ started to get twice the amount of Cheetos and also kept one or two packs in her go bag for Emily in case she wanted to eat them again in the future
