Duo Emotes?

[Rilifane]

... though for things like /carry or /piggyback one has to wonder how that would work with lalafell aswell as the very tall/heavy races. Could a lalafell /carry a Roegadyn?

Nah, the Lalafell l whips out a tray and holds it over their head for the Roegadyn to climb on. And then they run around with them proudly standing on the tray.
Or maybe the Roegadyn gets pointe shoes and stands on pointe on the Lalafell's head. With pink bow and all to tie them, fluttering in the wind as they move. Roega feet are to big to fit on the small heads otherwise.
