You ask Garen if he has a party trick and he starts bouncing his pecs.

To be elaborate the thing about Garen being a good cook, he isn't the classically-trained, foie-gras-and-molecular-gastronomy-type of good cook (though I doubt anyone was ever even thinking that to begin with), he's a make-mayonnaise-from-scratch-type of good cook.

"Garen would hate Shyvana!!" "Garen would think Shyvana is a monster!!" Actually Garen would view Shyvana solely as the thing she exactly is: a co-worker.
