The wonder in those scarlet eyes as he stares out at the distant snowy peaks and moving panoramic view ... it reminds Yzak of how little he's gotten to see and experience.

He just watches Blue's expression, the way his eyebrows shoot up at this or that in particular or the way he keeps his gaze on something, his own expression growing soft and fond. Blue is enjoying his view, and Yzak his.

When he feels the mouse's nose barely touch his hand when it sniffs at him, he peers down as it with a tip of his head, as if mentally asking "what?" He'll uncurl a finger toward it, having been working on making up for their initial rocky start.
