Derek is sitting on a chair behind the main nurses' station and eating potato chips. Cristina walks up. "My back's killing me." she whines, eyes halfway closed. "Get up."
Derek chokes back a ridiculed laugh. "Like hell I will." he answers through a mouthful.
"You came first! You've already been there for a while. My turn!" she fires back, ever-competitive.
Uninterested, Derek just puts another chip into his mouth. "That's right, I came first. Therefore, I get to stay. Go sit somewhere else."
"Fine. Whatever." Cristina rolls her eyes and flops in his lap, stealing a handful of chips for herself.
"What the hell?" Derek jumps in surprise. "Get up!" he says in a menacing tone, to which Cristina vaguely shrugs and steals more chips. Derek tries to force her up. However, she keeps her balance and turns to smack him.
Owen, who had noticed his wife and friend bicker, walks up. "Should I be worried?" He asks half-amused, half-worried after noticing their position.
"I've performed four back-to-back surgeries today, this is the first chair I've seen since 7 am and he won't get up from it!" Cristina grumbles, while Derek rolls his eyes in response.
"It's also the first chair I've seen in a while, and I came here first." He stated smugly. "And she's eating all of my chips."
Owen stares at them in disbelief for a while, and then he just turns around and goes away.
Derek and Cristina keep fighting over the chair and the chips for a while longer, when Meredith notices them and walks up.
"Should I be worried?" She inquires.
