Who: Nate and idk his BFF Pierce? What: It's Beer O'Clock. And discussion time. Where: T1. When: After Pierce meets his cheery niece Aura in a graveyard, and after Nate picks up Simon from the airport. LULZ. Warnings: This bromance is so awesome, it may kill you in the face fifty times.
Let us first start by traveling back in time a few years, back to the days of Stanford, keg parties, and stealing your roommate's clothing from the communal bathroom while he was in the shower. When it became glaringly obvious that Pierce and his biological brother David were meant to spend the rest of their natural lives in a love-hate roller coaster of angst and one tear (that they would blame on dirt in their eyes), Nate stepped in to fill that brotherly role. No one could take David the Anathema's place per se, but Pierce considered Nathan part of the family regardless. It was true that Nate was dedicated to his good friend and grateful for what he had done for him (money is important, despite people who will lie about it otherwise), but it went both ways - Pierce was always looking out for Nathan and he would do most anything for the man, which didn't make Nate simply a minion or someone who did Pierce's bidding. It was not a one-sided bromance.
He knew that when he called Nate, seeing if he was free to come up for drinks and a chat, it wouldn't be long before he climbed the relatively short distance to the tower and just let himself in. Most anyone else who did that would have gotten a katana blade in the eye right away but Pierce was expecting Nathan, so he only glanced up briefly before going back to rummaging through the fridge for beer.
"Alright, what'll it be: Dark Lord Imperial Stout or Westvleteren?" The latter wasn't easily accessible outside of Belgium but Pierce, of course, had connections to end all connections.
