Aw, had hope it'd be a surprise for you :(
But I do wish you and your family (Zoe and Biggles included) a wonderful and happy holiday!

Maybe this is a something new, in case you haven't had the time to follow up on duodecim.

These are other character's quote before they battle Tifa:

Cloud: "I never thought we'd be fighting like this."
Squall: "I'm not in the mood to listen to a lecture."
Terra: "I'll face you too."
Firion: "It's unnerving to lose your way in battle."
Garland: "Does your fighting spirit stem from your skills?"
ExDeath: "Both promises and hopes will be swallowed by the Void!"
Onion Knight: "Can you really fight with a figure like that?"
Tidus: "Let's do this without cutting any corners."
Emperor: "A spirited girl."
Cecil: "Let's try our hardest without getting injured."
Zidane: "Admirable and fearless; a good combination!"
Sephiroth: "It seems your hero isn't coming."

Victory - "You haven't trained hard enough - how ridiculous!"
Near-death victory - "Phew... that was a bit dangerous."
Defeat - "I've... lost sight of myself."
Defeat - "I... just wasn't strong enough."

Cloud's quote got me LOLed. I imagine Tifa thinking, 'We live together for two years Cloud. It's bound to happen.'
