Once Ondine & co. arrived, your first move was to jump in her arms, overjoyed to finally see her. While she had more than enough strength to catch you without stumbling, living in the depth of the ocean, where the pressure alone could kill a human, her lack of practice in using her legs caused her to fall nonetheless. It didn't stop the two of you to kiss passionately, almost like your lives depended on it.
Your mutual display of affection was, at first, what everyone looked at. But once the other merfolks separated, revealing a hidden Natalie Wave carrying her husband, Mark Neptune, bridal way, she became the new center of attention, especially after Amelia called miss Wave her sister.

They installed two of those in your sister's basement, one for bodyguards of each sex, one in a guestroom for Nat' and Mark, and one in your own bedroom. This last one was, at Ondine's insistence, filed with salted water so it would force you in your merman form.
After hurting yourself when you tried to move inside the tube the previous night, you were perfectly aware of your total inability to move correctly your tail, but you still found the method a bit forceful.
…That, and you secretly hoped for the comforting familiarity of your usual bed.
