Other friends that Eddie has known would not have taken him seriously (would not have picked up on the longing that even he didn't want to acknowledge there). The question from Angel startles Eddie a little -- prompts him to wonder...

Did he want to dance with Angel last night?

"Well... I didn't think you wanted to, since we sort of... wandered away from each other." Eddie glances down, keeps his eyes on the table. "We went as friends, right? But... you wouldn't have been interrupting."
