-Who is older? -- Izzy is. By far. Maria’s like, 17. Izzy is like hundreds of years old. Crazy shit.
-which one would eat peanut butter right out of the jar? -- Izzy. She doesn’t give a shit. Maria’s cringing - “Don’t you at least want some crackers? How can you just eat it like that?”
-what is the favorite eye color of each of them? -- Maria thinks all eyes look pretty. Izzy does too, but if pressed, will admit that she really likes brown eyes.
-Do they fight? Would they ever fight? -- Hell yes they do. Never physically (save for, y’know, the fight where Maria breaks her nose), but they argue a lot. Both think that they obviously know what’s best instead of trying to sit and work it out. It usually ends in Izzy losing her temper/yelling and Maria freaking out and then Izzy feeling like shit. So they usually end up working it out. Somehow.
-Pillow fights? -- of course. once they’re in a groove of “no one’s dead/dying/in the position of having to fight a king of something,” they do silly shit like that all the time.
-if they had to write about a summer vacation how long would their papers be? -- Oh lord, Maria’s paper would be at least 3-4 pages, with a proper title and page numbers and literary references and some sort of lesson learned at the end. Izzy’s would be like, a paragraph. If that. “This one summer back in 1847 I was in Greece when my dad decided to track me down, trap me, and cut off body parts because he was mad at me :) :) :) the end.” (Izzy is also the one that uses :) in the most passive-aggressive way possible.)
