Shen Yuan diligently copies all of these, even though he won't need the latter two much. Except maybe as questions, to be able to check in with Galahad. That's mainly what he needs this for anyway, but it's also just cool to see the different signs, how they correspond to words he knows. He's never been a particularly dedicated student, but if he thinks he were learning everything like this—comfortably ensconced in bed, hanging out with friends, with a real goal in mind and not just because he should he would have been a better one. He smiles at Galahad, and signs happy, happy.
