Sean Brennus/Strength
"Over time, life presents the Fool with new challenges, some that cause suffering and disillusionment. He has many occasions to draw on the quality of Strength. He is pressed to develop his courage and resolve and find the heart to keep going despite setbacks."

Sean is already pretty patient when it comes to his studies and his brother (anyone related to Eric is), but otherwise has a very cold exterior and chooses not to understand the ways of others - his arc is a journey to find compassion.
