this story might be much better with some face claims

Emma mills (later Reid)

teenager: 

adult (yes i love ouat shut up)

Mark Sloan (i also love greys shh)

Alex Sloan (no comment on this one)

Lindsay and Kate Sloan

Zack Sloan (teen wolf, my love)

Jasmine Dakota Reid

Rose Jones (i just love her in everything)

and all other criminal minds characters as themselves, also as a side character i didn't really know who should play Josh so you can imagine him for yourselves. just imagine athlete type of guy but also really sweet (maybe Tom Holland)
