He'd known.
He'd always known.
The way she reacted after the interview where he'd told all of Panem… all of district 12… that he'd been in love with her, told him that there was a lot… a LOT … of convincing to do so that Katniss would believe him.
So he wasn't sure why he was at all surprised to find out that it was an act on her part.
It stung a bit ,to be sure.
He thought that he'd shown her that he really did love her. Suspected that she really did care or she would have … should… have skewered him with an arrow instead of using the berries.
She'd as much admitted that she was more confused as they got closer to home. He should have accepted that.
But he felt that he was being used as a pawn. First by the Capitol as he told Katniss before up on the roof. But now that the games were over, he felt doubly used and he really did wonder if Haymitch and Katniss worked up the whole thing the entire time.
Maybe it had been a stupid thing to ask for separate training.
He felt ashamed and dirty. He'd thought… really thought… that Katniss had grown to love him.
She had gone looking for him after the rule change and when she saw how wounded he was, instead of letting him die, she'd lied to him and gone to the feast to get medicine that had saved his life.
Was he so starved for affection and attention that he had assumed that a 'showmance' was real? He wondered what Katniss would do if she was in his shoes.
It began to dawn on him that he really didn't know Katniss and maybe that was the problem.
He really should have known.
