Sun watches from the beach as Jin collects food from the tide pools. Michael approaches her to ask if she's seen his son, and when he leaves Jin becomes upset with her because the top button of her sweater was undone (Ep: 1x2, Pilot Part 2).
Sun brings a suitcase to Jin, but he says it's the wrong one and tells her to clean up her face, that she is embarrassing him. As she turns to leave, he tenderly tells her he loves her.
Sun has watched Kate and how free she is with her body and wishes that she could be that way also. Thinking she is alone, she removes her top to wash, and suddenly Michael comes out of nowhere and runs right into her.
