Ezio heads towards Florence, his mind scrambling for some clue telling him as to why Speranza left.

"TC" is obviously "Tarso Capitani", but why does it simply say "I know"?

What, he knows she's hunting him? What does he know?

He lets out an exasperated groan, slowing the horse down. He can't ride if he isn't thinking straight.

He climbs off the noble animal, letting it graze as he paces.

"Think, Ezio...where would she go?" he asks. "What place would Tarso go to? What place would be a great place for revenge?"

All at once, he stops, an idea coming into his mind.

Actually, it's more of a memory, from back in Monteriggioni with Speranza.

"What was his name?" Ezio asks.

"My fiancé's? Why do you care?" she asks, raising an eyebrow. He shrugs, and she smirks. "Piero. His name was Piero."

"Hmm..."

"Siena was absolutely beautiful. It was stupid of me to go there, what with Tarso having a base there and all. But, Piero thought it would be a nice change from the norm." She sighs, biting her bottom lip. "It was nice, until he was murdered."

Ezio closes his eyes, leaning back. "Templars are just...awful."

"Agreed." She laughs. "Oh how I would love to kill Tarso in the exact place he killed Piero. It would be bitter sweet...don't you think?"

"Siena! Siena, that's it!" Ezio cries, and his horse snorts in surprise at the sudden outburst. "Sorry nobile cavallo. Good news! I know where to find my bella rosa!"

In a flash, he's back on the horse, turning him around and breaking into a gallop towards Tuscany.

Nobile cavallo: Noble horse

Bella rosa: Beautiful rose
