(Catrina POV)
I slowly rise to my paws, wobbling away from the pool. I'm not used to walking on all fours.
I swipe my tongue around my mouth and flick my tail a little. Being a cat is really different. All of my senses are really sharp now, and despite the fact that it's just barely the break of dawn, I can see everything clearly.
"Hey!" one of the warriors with me shouts. "Who are you? What are you doing here?"
"It's me," I say. "Catrina."
He stares at me, appalled, and turns to the other three. They shrug, muttering things like 'Who else would it be?' and 'She does look similar to Catrina.'
They turn and head back towards the ThunderClan camp and I quickly leap to my paws to follow them, but topple over from losing my balance. With a hiss of annoyance I get back up and shake out my fur. Then I race after them.
(Willowstar POV)
I wake up with a content yawn. My dream was watching Catrina's vision at the Moonpool. I already know the perfect name for her.
When the patrol enters the camp with the cat version of Catrina hard on their heels, I leap down from the Highrock to greet her.
"Willowstar," she says, coming to a wobbly halt next to me. "I had this dream and-"
"I know," I say, "Firestar let me watch from his point of view in my dreams."
"Oh." She shifts her weight from paw to paw. "It's really different," she says suddenly. "Being a cat, I mean."
"I'm sure it is," I say. "I, um- Firestar explained something to me, too. You just change when you cross the Clan-Twolegplace border now, but he said you will be able to control it later. Your family, friends- he's gotten into their minds somehow, with the help of an age-old Shifter like you. They still think you're there, like normal. That fake version of you as a Twoleg is already programmed to do everything you would in every situation, so you can go back to Twoleg form whenever- taking its place- and only we will know which is the real you. It will disappear when you go back as a Twoleg and reappear when you leave."
She nods, seeming to at least sort of understand. "Like a copy of me living the human life that I can't anymore."
I sigh. "Yes," I say. "I guess you could say that."
"Okay." I wave my tail towards the clearing and she nods, disappearing in a throng of curious cats.
I leap up the Highrock to call for a Clan meeting.
(Catrina POV)
"Let a cats old enough to catch their own prey gather beneath the Highrock for a Clan meeting!" Willowstar calls.
I sit with the other cats and look up at her warily.
"Catrina," she calls. "Step forward, please." I slowly pad forward, nervous.
"Catrina, you have visited with StarClan and have become a cat like us. To be a full Clan cat, though, you must become an apprentice and train to become a warrior." My paws tingle with delight.
"StarClan," Willowstar continues, "I call upon you to look down upon this cat, who you have gifted with the power of shifting, as she earns her place in her chosen Clan, ThunderClan. Catrina, your new name will be Thunderpaw. StarClan has granted me permission to use such a legendary name for such a legendary cat. I will be your mentor."
The assembled Clan cats cheer and chant my name, "Thunderpaw! Thunderpaw! Thunderpaw!" and I feel it echoing around the clearing.
My new name is Thunderpaw, and I am a ThunderClan apprentice, and one day, I will be a legendary warrior, a Shifter.
