Rory was, indeed, holding something back - all of the drama with Fiona. But now, after his long and accusatory rant, followed swiftly by a deep, spiraling depression, Rory was too drained to talk about it. He felt uncomfortable at having kept something so important from Eisen for so long and he was sure that Eisen would be upset when he finally did break down and tell him, but Rory had already exceeded his drama tolerance for the day (probably even for the week), so he was all too happy to have the distraction offered to him.
"Thanks E. That means a lot to me." Rory looked over at his now-cold lasagna. "Right now, I say was stick our lunch... dinner... whatever meal we're having now in the microwave and break out some classics. Something romantic, even, in honor of your new relationship. Casablanca or Gone with the Wind or something."
Rolling over to the microwave, Rory popped his lasagna in and turned back to his friend, one eyebrow quirked in a much more normal, much less angsty, typical Rory expression. "So you never actually answered my question before. Were you out late?" The emphasis that Rory put on the last word of the sentence made it fairly obvious that Rory's question went beyond the time Eisen had gone to bed last night.
