Bill + Fleur
Fleur laughed. "No, nothing at all like them. Sirens have tails." Of course, Veela had their own unique physical features when they shifted form, but that wasn't something Fleur was capable of doing, so why point it out? She was more interested in talking about Bill's features, thank you very much.
She allowed herself to be led and raised an eyebrow as they walked. "Are you? Very strong, I mean. I may need proof of that before I go boasting that my boyfriend can beat up someone else's."
She winked at him as she settled comfortably in his arms, resting her free hand on his shoulder, letting fingers graze gently against his neck.
