"I'm a cavalier, so I'll be at a disadvantage without my chocobo. Still, I think I can manage something..."

...Like this broom. There's no harpoon here, but she does have this broom to work with. It's the best she can do. Once she has a hold of it, a white aura wraps itself around the fox as the flourish of her broom polearm still triggers one of the Divine Stances.

Right on time, too. With the arrow shooting in and the pirates alerted to their presence (specifically Baiken's perhaps), it won't be long before they get away with their iMogs.

"I'll make an opening for you; just let me take a shot!"

It's more of a statement than a request, with the way she readies slides into position by the door, risking that quick peek outside to get a look of the situation. Just remember everything Felena taught you about firefights, Tilly...

With her broom at the ready, the cavalier keeps herself pressed against the side of the door, taking aim with her lance and guiding the Light Arrow towards the archer. It may not hit very hard, but the chance to blind him is what she's going for...
