Because you don't seem to right now, Tseng. [Rufus doesn't respond to Tseng right away, looking at him. Despite the tension, he does have to remind himself not to get distracted by seeing how Tseng's wet hair falls over his shoulder, biting his lip for a moment before focusing on the issue at hand.]

I'm not expecting you to be his friend or play nice but we have an agreement on working together when needed since I see no reason to fight each other here.

[He knows Tseng doesn't fully understand, he can't since he hasn't experienced what Rufus has.]

I owe Cloud a debt that while he may not have done yet, I can't forget. I'm just asking you to please honor the agreement we made.
