The first time Watanuki walks back into that room and sees the pipe he just breaks down.
Maru and Moro have been quiet since she passed from existence but still they shadow him. They are quick to go to him as he collapses to the ground, wrapping themselves around him as they cry too.
They each rest a head against his shoulder, warm against his sides as the cold in his heart threatens to overtake him.
Mokona drops from his shoulder to his chest, holding him too.
"It's okay. We've got you. We're here too. We're not alone." They say in almost unison, voices shaking.
Watanuki shivers, clutching Mokona closer to him as the girls cling to him too.
"I'm sorry." He whispers into Larg's fur.
"I'm sorry that I can't take her place so easily. I'm sorry I couldn't save her." He sobs, wiping his tears with one arm.
"That's okay." Moro says softly, speaking out of turn with her sister for once.
"We love you, Watanuki." Maru finishes, both of them pressing closer to him as if he could stave off their cold.
"Yeah." Chimes in Mokona, voice thick.
Watanuki feels a small smile manage its way to his lips for a moment before it's broken by another sob as he hangs his head and just cries.
"Thank you. All of you." He whispers like a charm as if his words could protect them. He wishes they could.
