Fiona happily takes the opportunity to pontificate on the differences between silk and wool. (Insert technobabble here.) In fact, the dress she wore at the Grand Ball at the end of Tribunal likely had at least some silk trim on it.

She takes a good look into the cave ((Per 0 + Awareness 3 + die roll of 6 = 9)) before she enters after Tranquillina.
