Echo was aware that Narcissus wasn't happy with the fact that she had defied his edict to not clean, but as she tried to explain in halting sign language - halting due to contractions - she had woken up that morning and felt compelled to make sure everything was perfect. Thinking back, it was like she knew Bastian was coming and she'd be damned if he had to deal with even a spot of soap scum in his tub before his first official bath!
She could tell something else was bothering him but had no idea it was Daphne's presence, pushing the concern aside when Narcissus brushed her hair out of her face. Gasping happily when he called her love, a little confused because he had never called her that before, she nodded before holding tightly to his hand. Unlike with Daphne, Echo had no compunctions with gripping Narcissus' hand to help alleviate her pain. Maybe she could draw some strength from him to get through Bastian's latest attempts to escape.
