Having returned Margaret to Colin, Malin stood outside the Church's grand gates, where the cold breeze woke his overworked mind—instead of continuing to speculate where that damn Chaos attribute of Mischael's came from, it'd be wiser to ponder why he and Mischael had not come to blows inside Benevolent Hospital.
For starters, Benevolent Hospital may have a large Array, much like the Harvest Church of Carterburg possessed a grand defensive array that could transport all ill-intentioned folks into Subspace; the hospital's Array probably could influence the subconscious of both parties, preventing them from fighting within its bounds.
This was a guess, since he felt that whether it was Mr. Mischael or himself, whether they would be affected was indeed a question.
Another thought was—they indeed considered taking action, but ultimately chose to keep the peace under the influence of the Array and the responsibilities they bore.
