Following Death's unexpected
Valentine's Day gift, it had taken Castiel the better part of three days to find a suitable room, run a few tests to make certain he could manage what he had in mind and then implement the idea.
In concept, it was fairly straightforward, along the same lines as the Christmas gifts he had given to Sam, Dean and Bobby.
This, however, was on a much larger scale, and the complexity was an order of magnitude greater. The small memories-made-manifest he had given to his friends were simple affairs. Even Sam's laptop was inert enough to be more or less self-sustaining.
What lay behind the doors of what had once been a fairly large classroom, now standing idle due to a wayward staircase that rarely seemed to grant access, was going to take a great deal more power to activate and sustain. Blessed memories were something any angel could manipulate, but there were those in Heaven who specialized in the task, usually working in teams, and Castiel...wasn't one of them. Its creation had been a challenge and had already sapped his reserves quite a bit, but his connection to Heaven seemed to be intact and his energy replenishing itself normally, so he wasn't too concerned. It would, however, have to be temporary.
Obtaining a bouquet of fresh long-stemmed red roses had seemed like a prudent backup plan, just in case his primary idea fell flat, and it hadn't been difficult.
Delivering them...well. That was something else altogether.
After everything else was ready, it took him another forty minutes--most of it spent distractedly pacing a hallway at a safe distance from Death's room in Hufflepuff--to think of what he was going to say, then work up the nerve to go and knock on her door.
The poor roses probably wouldn't have survived the experience, if he hadn't been able to fix them three or four times along the way.
