Gwenaëlle doesn't have a dog, or any desire to fight with them - but she is awfully curious about more or less everything that's been going on around Skyhold, and when she'd heard the name Asher Hardie bandied about...it's been a while, maybe a year? Two? It is purposeful that she isn't entirely sure, but the insult is aimed elsewhere - at the affronted suitor who'd caught them - and she does not happen upon this lesson incidentally but comes down from the hold with her spectacles and her pen and observes.

Takes notes.

Enjoys herself, probably, she's always had a soft spot for watching warrior types do warrior things -

And waits until afterwards to say, "I finally met someone taller than you, Hardie, and it's an elf. Who'd have thought?" and simply takes for granted that she'll have been equally memorable.
