Pascal is really nice, and gentle natured. Euphy likes that, because she feels more accustomed to that herself. However, she worries that this is at the expense of Pascal continuing to carry guilt regardless of what everyone else thinks, even the people he wronged. And she did have a generous assist from Mark in knowing that he's a lying liar who lies with a smile, but I'm certain she would have figured it out anyway. So, she's concerned that Pascal hides his hurt with his smile so much that... it's hard for everyone else, and even possibly himself, to know when he's genuinely happy or when he's hiding the hurt with a smile.

C... concerned.

Reverse?
