I think that season fifteen should start with us seeing new or side characters for a few scenes (mostly to introduce a new conflict) before getting back to the main cast. I would love to see that the reds and blues, Wash, and Carolina stuck around to help the colonists build a new Armonia. There would be a gap of a few months and the Hargrove plotline would be all wrapped up and never seen. They could make a joke exaggerated all the things they did to Hargrove, possibly leading to a "that doesn't seem physically possible" callback. I think that it would be nice to have a few episodes mostly focused on the reds and blues adjusting and for the audience to mourn Church's character together. I was thinking a scene like this would be nice:
(On a balcony in a large city the reds and blues, Doc, Wash, Carolina, Kimball, and Dr. Grey all are waiting expectantly for the grand reveal of a large object covered in the square below.)
Kimball gives the order to pull the tarp and the crowd cheers. It's a statue of Doyle. There's a plaque at the base reading:
"Courage is not the absence of fear, but acting in spite of it.
--General Donald Doyle"
Wash reaches over to put a hand on a silent Caboose's shoulder. "How about some confetti to celebrate?"
Caboose looks at Wash and says sadly, "Why would there be confetti if Church isn't here?"
"Caboose--" Wash begins and continues to talk in the background.
"Does this mean I'm in charge of confetti from now on?" Simmons asks Sarge.
Grif snorts while Sarge replies "Are you telling me that you haven't been following protocol by being prepared to launch confetti at any moment?"
"No sir! I was just, um, clarifying," Simmons stammers.
"If we're celebrating, then how about we break out some dance moves? Everyone, do the Chupa!" Donut says and the Reds groan. He continues to say 'do the Chupa' over and over. Lopez approaches Carolina.
"Please make the pink idiot stop," he says in Spanish. "I would suggest throwing him off the balcony, but he will only come back." Tucker steps forward.
"Why the fuck doesn't Church get a statue?" he asks. Everyone falls silent, even Donut, who has snapped himself out of his disco fantasy.
"It's different with Doyle, Tucker," Kimball says.
"They don't care about Epsilon. They don't see him as a hero like Doyle," Wash says.
"So? Make them know about what he did! Make them remember him!" Tucker yells, his voice breaking.
"Tucker, I can't do that. I can't make them have memories of someone they never knew. Isn't it enough that we remember him now that he's gone?" Tucker turns and grips the railing tightly.
"Church isn't gone, he just isn't here right now," Caboose recites.
"No he isn't, Caboose!" Tucker says, turning around. "Church is--"
"Tucker!" Wash says sharply, cutting him off. "Let Caboose believe what he wants to," he says quietly.
"So we're just supposed to forget about the fact that they are oblivious to the person who is responsible for saving all of their lives?" Tucker asks.
"What do you want to do, Tucker?" Carolina steps forward and asks. "Hargrove is dead. There is no one left to blame or punish for what has happened." Tucker says nothing. Carolina walks until they are face to face. "I'm not saying you should be over this by now. I'm not saying you will ever be over this loss. I'm just warning you of what can happen if you let your emotions lead you astray." She turns to leave, but Tucker speaks.
"Like you know? You hunted down the Director and helped tear apart your old team!"
"Sometimes lessons are learned through experience. I would not wish what I have gone through on anyone, especially any of you. I will do anything in my power to help you not have to learn that lesson firsthand, whether you wish my help or not." She leaves as Tucker turns back towards the statue and leans against the balcony, brewing in silence.
Doc carefully approaches Tucker. "Yoga is an excellent exercise to relieve stress and counseling would be a great way to work through psychological problems." Tucker says nothing. "You know, for people so concerned about remembering loved ones, I don't know how you could forget about me," O'Malley says and all the others slowly leave. Simmons begins to blame Grif for losing Doc and their squabbling fades as they leave. (pan back to Tucker at the balcony.)
"I'm sorry Church," Tucker says. "You may have a prick, but you deserved so much better than what you've gotten." He goes inside the building, shaking his head.
