David, love, of course he is worth drawing and caring for. And maybe Balthier is a little sentimental, and a little nervous, and wanted a keepsake and a memory for when David was away from him, for when he inevitably left. Though he's less concerned about the latter now.

"They're generally in chronological order, yes." He chuckles, pleased. "I'm glad you like them. I was afraid you might find it clingy, though I admit I'm rather proud of myself for you not realizing. Normally you can see right through me."

And there's a question hanging in his throat now. He takes a sip of tea. He'll let David look a little longer, doesn't want to rush this moment with another. Because sharing a sketchbook is high on Balthier's list of intimate gestures, and he's savoring being seen and delighted in as well.
