Isaac is a sweet, curious, calm guy. He can be shy at first, but once comfortable he opens up and enjoys playing and engaging openly. Isaac's quiet non-disruptive demeanor runs the risk of masking things -- anything from a lack of understanding content, to a need for more work, or a big feeling present on his mind. At times he benefits from being nudged to work or engage more deeply, once he gets started he can be quite focused and intent.
