Mary was having such a great time she almost forgot to make sure Rita didn't run off. She heads upstairs excusing herself to see if Rita was in her room. Mary knocks on the door, "Rita? You in there?" After a moment, Mary opens the door to see the room a complete wreck as if somebody planted a tornado in the room and that was definitely not like Rita to have a room a mess like that. Something happened to Rita. 

Mary's brain began running at a million miles an hour thinking of every possible thing.  She goes to turn around when Rick appears in the doorway behind her, "H-eerrup- Have you seen Morty? Summer said he ran off with Rita. A while a go." Mary frowns, "Rick I think something happened to them, Rita's room never looks like this." 

They are both fourteen-years old they will do what they do."  
Rick goes to take a sip from his flask, Mary grabs out of her hands before it teaches his lips, and puts it in her coat pocket. Rick furoughs his eyebrows together, "w-what the hell Mary?!"
"Rick this is not normal you have to believe me."
She makes eye contact with Rick to plead her case, Rick sighs and gives in. 
"y-y-you know it's sort of unusual for Morty to run off at a time like this.  L-let me take a look."  Rick moved past Mary into Rita's room. Rick kneels down to look at some crumpled papers. He then pulls out a device and scans every wall projecting some sort of past scene. Rick frowns, "Shit Morty." He mutters.
Mary couldn't help but watch the hologram of Rita fight beside Morty. Mary sits down on Rita's bed and covers her mouth in shock. Tears dribble down her face like a faucet came on, "I might never see her again..."
Rick spins around on his heels to face her and kneels  on one leg. 
"Okay so from what I just found, there was a doppelganger of Morty with an eyepatch push them into a portal.

"They are gonna die." Mary gets up loosing her cool.
"Woah,woah,woah!" Rick grabs Mary by both of the shoulders and shakes her, "get ahold of your self Mary, it's not your fault."
Mary brushed Rick's hands off of herself and walks over to the window. She didn't know what to do at this point but go to the police, "you're right...It isn't my fault. It's your fault."
Rick frowns and crosses his arms, "you-you  are in shock right now,  you are just trying to put your blame somewhere it doesn't belong." 

Rick opens the window and holds out his hand to Mary,  "I need you to come with me." 

Mary doesn't hesitate and takes his hand as they both jump out of the window into a green circle Rick created on the ground. Mary feels a slight buzz at the back of her skull when they hit the concrete of the Smith's garage. "whoa how did we get from there to here?" Rick rummages around through his stuff, "No time to explain we have to go."  He creates a second portal on the wall, "Lets go." 

Rick grabs Mary's hand and jumps through the next portal. They appear in some sort of  colorful crystalline dimension full of strange creatures "Welcome-errup-to dimension D-zeta 455. What Whatever you do don't touch the plants Mary, they are cannibalistic trees that will eat us and we'll be stuck here forever." Mary found that that sat a little heavy on her shoulders she just hoped that Rita didn't come here. "I doubt that they would be here."   

Just as Mary said that, some of the nearby trees begin to chime and rumble together creating a beautiful sound, "Uh Rick?" Rick looks up from his watch, "what? Oh!"  He turns around to see exactly what Mary was staring at, a giant crystalline tiger looming over the trees barring down at them, "Run Mary Run! for your life!!!" Rick pushes Mary in the opposite direction, "Of all things it Had to be a tiger!" she yells breathlessly at Rick, "This dimension is Hell!" She notices the trees begin to shoot tendrils at them with what looked like barbed crystals, "Believe me honey, this is a paradise compared to some of the other dimensions." 

Mary glances at Rick  noticing how youthful he looked running for his life right now. She notices some black crystalline creature jump out of the corner of her eye and attack the giant tiger the two giants begin to battle it out giving Mary and Rick a chance to escape.  "Circle of Life." Mary yells.  

The two stumble upon a shallow dead end cave. "We should camp here tonight." Rick announces. Mary sits on a crystal rock  and looks out at the darkening sky. "Yeah I hope we'll be safe." 

Rick smirks, "Don't Don't you worry about being safe, we'll be fine."  Rick pulls out a small gadget from his small backpack and places it in the opening of the cave, he then scans the backside of the cave, Mary thinks back to how youthful Rick looked while they were running for their lives. "How do you do it Rick?"  

"Do what?" Rick places down his device at the back of the cave and activates something on his watch.

 "Be so youthful." Rick tosses Mary a sleeping bag from his backpack and pulls out a small bottle of rum.  "I don't know." he finally answers. Mary guessed that here was no answer for holding up a youthful lifestyle. "I-I thought you might need a drink, so I brought you some rum."  Mary squints at his backpack, "How much can you fit in that backpack?" 

"As much as I want, it takes the molecules of anything I put in the backpack and condenses them into tiny particles, and-and when want something, I think it, and it appears into my hand." 

Mary holds her hand out without a word and asks for the rum.
