Please picture Shiro refusing to ever break down or show that he’s suffering in front of his team, because he’s told himself over and over again that he needs to be strong for them, that he can never show weakness, because he has to be their foundation, their unbreakable unshakable leader.
Imagine all of that stubbornness and resilience falling apart the second Matt pulls him into his arms and whispers into Shiro’s ear that it’s okay to be sad, it’s okay to be scared, that it’s okay to not be okay. Because Matt isn’t Team Voltron, Matt isn’t Altean royalty, Matt is just Matt, and Matt has suffered just as much as Shiro has if not more, and Matt knows, Matt knows.
Please picture Shiro refusing to break until Matt is there to hold him, until Matt is there there to tell him it’s okay, and then he just buries his face into Matt’s bony (too bony too thin) shoulder and just lets it all go and finally shatters.
Please picturing Matt being the one to help Shiro break, and then being the one to help put him back together.
