Week 1: Pragmatic about matters of killing, yet seems to be an idealist. Boa's not sure what to make of him. Week 2: Shirou turned out to be a very self-sacrificial person. Boa can respect the resolve it takes to offer your life for someone else, but he also just doesn't relate at all. Week 3: His near-comical devotion to a clean kitchen is almost endearing. Week 4: Boa was very ready to accuse him of murder and he was also wrong about that, so that adds a minimal level of awkward. Week 5: Shirou was very ready to execute Boa, which Boa cannot blame him for, so that's fine.
