As a superstitious person, I'm not sure if 13 days is good or bad, but I'm leaning towards good. YAY! Anyhoodlum, please R & R, but don't flame. Otherwise, I might have to donate your flames to the KJBWFF (Kill Justin Beiber With Fire Foundation).
Every member of the team had their figurative umbrella, the shield to block out thoughts of the depravity of human beings that took it into their own hands to play god, to kill people as destroy them in the most disgusting of ways.
For Hotch and JJ, the two parents of the team, their umbrella were their families, specifically their wonderful sons, who replaced their hope in humanity with just a simple smile, blocking the rain of blood with their very presence. It was in watching Jack dash down the soccer field that Aaron Hotchner was able to imagine that the world was an inherently good place, run by good people, even though he knew the opposite was often true. For JJ, just seeing Henry's blonde locks flop into his face when he was thinking "Like Uncle Spence" was more than enough to restore the hope in people.
For Derek and Penelope, their solace was in each other. Penelope would keep Derek's world from being blackened by those around him, and he would, in turn, stand by her, defending her against both UnSubs and simply those that would attempt to destroy her sunshine, a much-needed light in their world. In truth, their over-the-top phone flirting was as much for the others as it was for them, but it was nonetheless their way of remembering that not all of humanity was as depraved as those they saw daily.
For David Rossi, his protection from the darkness of their days was once Erin Strauss, even though he thought his team might not have approved, but ever since she had been gone, he'd taken to finding peace in the woods of Little Creek, and in the kitchen where his family had taught him to cook, even when he didn't want to learn. Now, he would teach his new family, a tradition that had stemmed from Emily Prentiss' "death". His umbrella from the deluge of corpses and violence was in the little things, and in his pseudo-family.
The last of the team, the youngest and most vulnerable, found peace in his facts, using them as his own umbrella to shield himself, but it had holes, one especially large one in the shape of the state of Georgia, and in the point of a needle, which had been sewn shut by the metaphorical thread that was the rest of the team. As long as his team and his mother were safe, then his umbrella could stay together, but, should something happen to them, like with Emily's "death", the seams would pull apart, no longer protecting him from memories he'd rather forget. Of course, with an eidetic memory, he could hardly forget, but he could try. In doing so, he'd destroy his own life, but sometimes, it seemed worth it. Those were the times he needed his tea
Because they could help him to think of other things, which his books, his statistics, and his facts couldn't do for him.
