My apologies to any chess players out there, as I know I'm using some of the terminology wrong; I took artistic license and also am a horrible chess player. The dialogue comes from episode 9x2, Deadly Situation.
.o.o.o.o.o.
It's a careful game they play, like a delicately executed chess match. And they are experts at playing each other to a draw.
He opens with a bold move.
"So are we going to talk about it or what?"
"Talk about what?"
"Syd, you kissed me, come on."
She moves to block.
"You know, Walker and Alex, they landed safely. I was excited. It was a celebration kiss."
He stubbornly sticks to his original strategy.
"It didn't feel like a celebration kiss."
As she blocks him again, she takes a jab at him, trying to get inside his head, rattle his confidence.
"Trust me, if I ever kissed you for real, you'd know the difference."
So he tries another avenue of attack.
"Why don't you let me see if I can tell the difference?"
And now she's the one rattled by his unexpected, forward action. Her next move is amateurish, clumsy, leaving herself open to attack.
"You want me to kiss you?"
But he doesn't press his advantage; in fact he's now retreating. His next move is throwaway, just biding his time and waiting for her to decide how to respond.
"That's your call."
Despite his earlier retreat, it's a daring maneuver. If she stopped to think, she'd realize the risk he took leaving himself vulnerable like that. But she never does. All she knows is he's playing erratically; this latest move seems a sacrifice of a closely guarded piece, and that makes her suspicious of his ulterior motives, suspicious that he's setting her up for a fall.
She kicks him hard, knocking him to the ground. "There's your kiss."
So he walks away.
Stalemate.
And so ends another successfully unsuccessful bout between two players who are both so relieved not to have lost the game that they keep forgetting that no one wins when the game ends in a draw.
