A very timely roll. Morilla's skill and grace at moving through crowds is specifically called out in her description.
Each time Tiber draws near enough to make eye contact with Lady Morilla, she smiles and slips through the crowd with a grace that fish in the sea would admire and dancers at court would kill for. Eventually, she lets herself be caught, saying, "An athlete like yourself belongs in the coliseum, not these stuffy halls." After reading the letter, she says, "Please return in a minute."
When Tiber returns, she hands him two letters. "The first is my reply to Martella, the second for Duke Centimus. I believe he can be found in the archives."
