Shea was battling with her mind of heart so it went out of her head that she should ask about his behavior.
Shawn let her eat because he didn't want her to panic thinking somebody was tracking her.
After breakfast, Shea wanted to run from there. For that, she needs to look at him and say goodbye.
She made her mind that she shouldn't freeze up like an idiot and turned to him. She didn't get the chance to speak.

Shea first looked at what was inside the transparent tube before revealing promptly, "When I was picking my thing from the floor, it was next to my lipstick."
Shawn was pretty sure, it must have fallen from her bag. So he first needs to know if it was with her to track her or him or a darker plan.
He plainly asked, "Do you know what this is?"
