Need Ditto and Larvitar

[Irides]

Hellooo, I looked it up how to get Ditto and I think I missed it? I know I freed all the Pokemon in the Cages and I have the others but I cant find Ditto in my PC. Dunno what I did back then, had a few months break from Reborn until i played again. Is there another chance to get it? And for Larvitar, I really want it in my Team but it looks like there is a Special Encounter much later in the Story... I am post City Restoration just now. Maybe someone would trade me one? That would be nice.

I can trade you both
