For any personality:

Grandpaw [NAME] comes over to [CUB] and starts ranting about some crazy old apedemak story. What goes on inside this crazy lion's brain?

Interaction for Chivalrous (Good):

After Grandpaw [Name] caught [Cub] cheating at a game, he gave the cub a long lecture about honor and morality. [Cub] meekly promised to never do it again, however you aren't sure whether he/she is truly sorry or just wants Grandpaw [Name] to stop going on and on...

(Could also work as a pep talk)

Peptalk for Humble (Good)

You see [CUB NAME] approaching [GRANDPAW], sniffling as they ask how [GRANDPAW] was such a good king, and confessing that they feel like they feel like they’ll never be good at training. [GRANDPAW] pats [CUB NAME] on the back, telling them that one day, when they’re big and strong, they’ll be better than [GRANDPAW].

600th support!

perhaps training, where any evil/snarky grandpaw can just start laughing his ass off?

'(grandpaw) falls over laughing as (cub) fails their training.'
'(cub) makes a mistake, and (grandpaw) begins to laugh so hard that he cant breathe'

stuff like that
