I've killed bigger men than him. Being big doesn't help if you don't know how to fight.

[She sighs.]

Also he was...nice? Maybe too nice. Before time began going out of order, one of the girls here passed out in the kitchen. He and I were in the area when it happened and his first instinct was to carry her up to her room. He even stood there till she regained consciousness.

Maybe he was tricked by whoever killed him? Not suspicious enough to think something could happen if he was alone.
