You always knew Rosa was one to get herself in mischief to survive, doesn't matter how risky it was. She went from pickpocketing to infiltrating high-security buildings, which almost got her killed one day. But she kept on going in that dangerous but thrilling life in Venice.
One day, you were going to buy her something for her birthday. When opening the chest where you kept your money, you saw it empty. Not even a single Florin was left. After analyzing all the suspects, you concluded. It was an action made by Rosa, perhaps while you were sleeping. You always knew how sneaky she was, but you somehow learned to identify the mischief she did.
After finding her near the Palazzo della Seta, you confronted her about the robbery done in your sleep, which she first denied. "I haven't done such thing, stupido bastardo."
