"There are always Plans, little brother. Always, even if you don't know them." It wasn't augmentative, it simply was. Death himself had plans and designs, Castiel's radical beliefs didn't change that fundamental fact. Everyone had a plan. "And while I do applaud loyalty, it's not my approval of it matters." He was still - always would be - bitter about Michael's betrayal. If loyalty to family mattered...Michael was the most loyal.
