Caspar's laughter is genuine and not at Harrow's expense, so he can't help laughing back. They've rediscovered common ground through salty language. This is what it's all about! Adia has to go and be a stick in the mud about it, but Harrow doesn't lose his smile.

When Harrow gets the drawing he immediately nods. She's drawn the situation pretty succinctly. But when she draws the question mark and looks at him expectantly he's momentarily confused. He scoff-laughs and points to himself, and with an incredulous look on his face says something in Space Swede that can only possibly mean, You think I, a dumbass, know what's going on here? He laughs again and shakes his head.

The shaking slowly draws his attention back to the art. Wait. Wait, there's writing there! He snatches up the paper and brings it close to his face to squint at what's been written. He knows those characters, but not those words! Still, he can try to read them, right?

"Doe yow k'nove vhat hap-pen-ned toe the Nexoose tr..." He clears is throat. This is a long foreign word here. "Tran...slaughter?"

He raises his eyebrows at Adia. He can read it! But he... Can't read it. Here, give him that writing implement, let him try. In a free space on the paper he writes Können Sie dies lesen?

What incredibly neat handwriting. It doesn't fit his personality. It's more like he learned to write by copying printed text, serifs and all.
