I swear everyone says keefe is so hard cast (he's not, Walker Scobell is basically perfect, actually quick story: I've seen two people cast Walker as Dex and each time I'm like NUH-UH)
Anywayyysss, Dex is hard to cast because he truly looks like a mature 10 year old but at the same time I couldn't see a 10 year old playing him for obvious reasons so after loads of searching I finally found a few people.
Okay and guess what there  are MULTIPLE OPTIONS which is honestly so shocking because before it was so hard to even find one!!!!

First off is Diesel La Torraca.

Then Christian Convery.

Luke David Blumm is the third one.

Charlie Stover is the fourth one.

Also he works with Pippa on a different project (one of the Bex fancasts)!!!

And then Freddie Spry.
