Prompt: "I think we need to talk." - Godzilla x Mothra x Rodan x Ghidorah - Kaiju Version

(POSSIBLE SPOILERS FOR THE [ kaijushippingverse] STORY INCOMING! But only if it ended in the OT4… Related to the crack kaiju OT4 [Mothra x Godzilla x Rodan x Ghidora] created on tumblr between me and friends.)

"I think we need to talk…"

Godzilla looked away from the little ones playing on his tail to his Queen. Mothra had an unease expression, her antennae hanging low and her fluff standing on edge for some reason. There was no need of any more words for the King to know there was something worrying his mate.

"Alright, playtime is over…" He said, getting up and lifting his tail, dropping Fuego and Yuzume on the ground. The kids squeaked in complaint. "Go bother your brother, or your papá… Dad and mom gotta talk." The kids did just that, running away to find Rodan and Ryūsei somewhere around the island.

Godzilla followed Mothra to a more private place inside the cave.

"What's worrying you?" He asked calmly as his mate rested on top of a rock.

"I've felt him…"

"Who?" Godzilla asked.

"Ghidorah." Mothra said simply, her antenna vibrating softly as she trilled the name of the fallen false king.

Godzilla didn't know how to respond to that for a moment.

"How?" He asked once finding his voice.

"In between realities…" Mothra said. She wasn't going to explain it all to the King, mainly because he never understood it very well. But on the very least he had a basic idea of what she was talking about: the place where she went right after she died, before going back to a new material body and finally returning to the world of the living. "He is coming…"

Godzilla huffed low, knowing very well what that could entail.

"How long?"

"Not too long…" Mothra trilled softly, in an uneasy tone. Her eyes vague, not focusing on anything in particular. "He is recovering his material form…" She turned her eyes back to the cave's entrance. Nothing could be seen from there, but they could hear the voice of Ryūsei talking with the youngest titans. "I worry… About our arrangement…"

"If he has a problem with it, we'll take care of it." Godzilla growled softly. "Rodan is our mate as well. Of his own free will."

"Indeed…" Mothra trilled again, brushing her smaller pincers together.

There was silence between them. The sounds of nature and the children playing being the only sounds around.

"Should we tell Rodan?" Godzilla finally asked.

"No." Mothra sounded serious, way more than before. "Let's wait."

Godzilla huffed in agreement. He studied his Queen, she was still tense, eyes vague, as if she was disconnected from reality – probably following Ghidorah's "steps" in that other dimension she knew very well.

"Goji…" Mothra said, her antennae standing up.

"Yes?"

"He is not alone…"

"What?" Godzilla thought about who could be together with the false king and he felt something tight on his heart when he thought deeply about it. "Who…?" He believed his Queen's words no matter the craziest things that she sometimes spoke about, but that… It couldn't be, could it? "Not–"

"Yes." Mothra chirped, a weird noise, shaky and weak. "It's Hime." She raised big blue eyes to wide small ones. "He is bringing her back to us…"
