Literally everything about the Fishing Rod Incident is just peak sibling energy. Pearl doing something dangerous and joking about it to the others. Grian watching her and calling her dumb but instead of stopping her he just goes "oh but what if we made it even better". The two of them laughing it off because even though it's very possible that Pearl could die she hasn't so far so "iT mUsT bE sAfE". And as soon as they get in trouble Grian immediately turns on Pearl like, "oh it was all her fault, she coaxed me into it you should be mad at her not me", thinking that Joel and Etho aren't that mad at them and will most likely just burn her house down or kill her dog. But then they kill her and Grian's like "OH NO DAD AND DAD ARE ACTUALLY MAD ABORT ABORT ABORT RUN AWAY RUN FAR FAR AWAY".

Also Scott going "guys this is a bad idea, guys here are all the ways this could end horribly, guys if someone gets hurt you're gonna bring me down with you, guys cut it out or I'll tell on you" and then as soon as it all goes wrong he's just, "I TOLD YOU SO NOW DAD AND DAD ARE GONNA PUNISH ME TOO EVEN THOUGH I DIDN'T DO ANYTHING THIS IS WHY I DON'T SIT WITH YOU GUYS AT LUNCH".
