The "Tea House" organization
I think it would be a good point to have an explanation post for the "Tea House" and how everything works in there.
As it was said, the "Tea House" is a very specific complex. Initially, it was a correction jail, just in another words, and it was sponsored by Senate. Also not every criminal was sentenced to there, it was Darklight's decision, so she often was present on court sessions listening, watching and searching for new patients. That's what she called them from the very start. She took only those, who was forced into crime by people and conditions or have so much guilt to deal with. Especially she sympathized victims of Senate's dirty games, and Sentinel hates her for this still.
After some years, when the necessary employees were hired, there were a lot of other clients not connected to crime. That's when the "Tea House" became not only the jail, but also a rehabilitation centre and social centre. Darklight hired more specialists to have more clients. It opened it's doors for victims and ordinar citizens.
When the war started Darklight found herself having various friends with benefits and sponsors, while Senate started threatening her to stop her frivolous charity actions. Also when the war came, it was Darklight's "charity actions" and willingness to have good relationship with both autobots and decepticons that saved her project safe and made it a neutral territory. No one had rights to claim it.
But since the "Tea House" started accepting visitors from both sides and taking people who wanted to hide from war reality, "O" group had to organize the visit schedules to make it impossible for soldiers of both sides to meet each other and have confrontations. Also Darklight made it the main rule for her workers and clients, that all information said in these walls stays in these walls. Information stays strictly confidential, and breaking rules have consequences. For clients it's inability to visit the "Tea House" anymore and for workers it's fines and administrative punishments. Discussions are allowed only between workers, who stays indoors.
Next the building itself. There are four campuses connected by hallways. Each campus has 2 floors. From above it looks sorta like a three-rays star.
First one is an administrative campus, it's in the centre of the whole complex. It's a reception post, a common dining room, a medbay and hallways to other campuses on the first floor, and a call-centre/announcement centre on the second floor, where the "Operation" group works. Also it's the only campus that has the third floor. It requires special-access cards that only the "Attack" and the "Defense" groups members have.
Second campus is technically a dormitory. It was projected for workers of the "Tea House" and some clients, who have to have a long-termed courses or have no place to live. The person who makes decisions about movements in is Darklight. Also there's the location of the bunker for "special occasions".
Third campus is a working campus itself. There are only session rooms for "Regular" group on both floors. Even Darklight's office is located there, cus even though she's the owner of the complex, she has her clients and visitors too (what a busy woman :D)
And forth campus is so-called "mental wellness rooms". There are a Wing's chapel, where he keeps the special room for "honoring the dead ones" (his initiative that unexpectedly turned out to be really required by local workers and clients) and the art room (for hobbies and special common art-therapy sessions) on the first floor, and a greenhouse on the second floor.
So, that's all for the complex's building itself. Next we move on to groups of the "Tea House".
Every worker and client there is in special group and have it's letters on their badges.
"Regular" or "R" group. It's just regular workers and clients. Nothing special there, just the majority of people of this facility. There are Rung, Drift and all the specialists and clients.
"Medics" or "M" group. Technically, it's everyone who has the medical degree. Officially there're only two medics, who are Lineup, who is a nurse, and Wingscream, who is a surgeon.
"Operation" or "O" group. These are people who make announcements, notifications and guide the last two groups during... "special occasions". And there is also Darklight as a big boss of the "Tea House".
"Defense" or "D" group. A special group of 5 people, who evacuate "R" and "M" groups during attacks. These are people, who perfectly know a building plan and can lead a mass to the bunker. They are also capable of fighting. They have some guns and other weapons. The ruler of the group is Wing.
"Attack" or "A" group. It's group of also 5 people. These are former soldiers, mercenaries and assassins. These are people who were specifically trained to fight and kill. Their role is elimination of any threat. Group "A" often works together with group "D", when the second ones can't handle the situation alone. The main in group "A" is Monochrome.
