One week after revelation
Twilight Sparkle endured alongside Tank. The age old tortoise seems to finally have understood what has happened to Rainbow Dash and for the past week he has not had food nor water. The it was hard for Twilight to see the animal that has been the rock in the stream of sorrow she was drowning in start to sink down to her own level of sadness.
It looked as if Tank was starting to get more and more tired as the days went on. This lethargy was a sign of the oncoming winter months that he was to sleep through and twilight was scared for him. He was not eating enough and as hard as she tried he simply refused to accede to her pleas. Winter was coming in three days and tank did not seem to be ready to endure the hibernation as he was now. Twilight Sparkle didn't want to see Tank die so soon after Rainbow had passed but she couldn't do anything to stop the spiral of depression Tank had fallen into. During this train of thoughts the titanic tortoise had somehow vanished.
Twilight knew exactly where he had gone.
POV Tank
It was a dreary day in the graveyard and the tortoise was sitting next to the grave of Rainbow Dash. The polished quartz marker had a dull sheen as the sun tried in vain to pierce the overcast weather that had been an almost constant for weeks, seemingly in mourning as well.
Tank was here to prepare a place to hibernate this winter, as if to reminisce on the first winter he and Rainbow spent together only with the roles reversed.
He then dug into the ground and slept
POV Twilight Sparkle
Twilight found where Tank had gone but it was to late to move him, lest she hurt him doing so. The purple alicorn knew it was now a waiting game to see if the aged tortoise would come out of this winter with his life intact.
Twilight Sparkle endured.
Tank never did wake up and Twilight Sparkle was alone again.
