Rory was so surprised by Eisen's entrance that his whole body spasmed, causing a rare grimace of pain that Rory quickly covered with surprise. "Ei-Eisen! I... um..." Shit. Well so much for that secret. "I'm sorry," he apologized as Eisen walked over to him. "I should't have picked it up." He was about to set the guitar back on its stand, but Eisen had already crossed the room and was repositioning his fingers to form a D suspended chord. He was quiet for a few moments, trying to process how he was going to handle this. It wasn't that he was trying to keep something from Eisen - as he had been with the Fiona fiasco - this was something... different. Deeper. He felt almost naked as Eisen suggested little improvements and an overwhelming question seized him.
"How much did you hear?" Rory asked quietly, ignoring the question that Eisen had posed. For this moment, Rory's need to gauge Eisen's reaction was more important.
