Cass was so utterly unprepared for what came that he simply sat there, easily letting Percy take over and answer Aiden's questions. But still it wasn't the questions that made his jaw drop, it was the answer.
Had Percy just admitted that he loved him? To his son of all people in the world? Then again he'd admitted it to others before mentioning it to Percy so maybe it wasn't so strange but it was still a very odd feeling. Somewhere between wanting to grin without stop because Percy had finally got some courage to admit it, and shock that it needed to be Aiden to bring it out of him.
His attention, snapped back though as Percy went on, and he looked down at Aiden, wanting to assure him of the same thing, yet not sure that it was what he had asked in the first place.
'Was that what you wanted to know?' he asked softly.
