It responds readily. "Permission granted; alts of Villanelle are good passengers. I have informed the crew."

Then she sees no problem materializing them on board!

Villanelle was on the main deck, fortunately, sketching the sprawling port that Serenity is currently docked at - the exceptionally strange sprawling port, a sky of brilliant swirls of light casting scintillating rainbows over a city made of spires of white stone and glass - many of them floating in midair - high arches forming busy walkways between the towers, numerous tiny sky-boats flitting around like birds, larger ships like Serenity in the chaotic port. Many of the people visible from the deck are obviously nonhuman, some humanoid with wings or tails or oddly colored skin but many strange - a large blurry ¿cat? purchasing fish, a floating eyeball wearing an out of place jaunty hat in a heated argument with a dockworker, a serpent with arms loading crates onto a ship...

She bounces up from her seat - she has the same face as Bellona - with a welcoming grin. "Welcome to the Serenity!" she says. "I'm Captain Villanelle. Are you looking for a ride - ?"

They're too busy staring at the city to answer. 

"Hello, Captain. At least one of them, I would guess."

That draws Bellona One out, at least. "We're trying to head to all different worlds - uh, long story short, we can't use our kind of power if we're all three in the same universe. Dunno if Zera was intending to drop us all off here for you to do the moving, or leave only one of us here - ?"

"Serenity isn't that fast, so getting you guys to two or three different worlds might take a while."

"Probably only one of us will stick around here, then," Bellona One says. 

"I can handle moving the others on," she says. "I'm Zera, by the way. I don't think we had a chance to meet when last you visited my world. The one with the dragon, where you dropped off that ninja girl with the eyes."

"We didn't! How's she doing, by the way?"

"Quite well, as far as I'm aware. I believe she is having fun and making new friends."

"Terrorizing the locals?"

"Only the ones that deserve it."

"Naturally."

At this point, the other member of the crew shows up. "Serenity said there were new passengers- Oh. More of you."

"One of the best possible surprises."

"Definitely up there."

"Probably only surpassed by more of you." Wink.

"Not sure I could handle that. I'm Ellie, by the way," she says to the newcomers.

"We're Bellona." She seems... Familiar. (Also her name is really close to El's - weird coincidence maybe but there's another version of them here - )

Bellona Two puts it together first and glances at Zera - "Is Ellie an alternate version of El? Like us and Villanelle?" What's going on with that, anyways, like the existence of four Bellonas made sense. 

"She is, yes."

...Huh. "Guessing you two aren't sisters, though?" she asks Villanelle and Ellie.

"No, we aren't. Not even born on the same planet."
