Special Heroes who are young but dependable will appear soon!

We're definitely getting kid Chrom, but trying to think who the other kid would be. Not guessing Robin because they don't meet Robin until adulthood. We just got a Cordelia (as a duo backpack but still counts), so very likely not her. I could see a young Emmeryn to round out the royal siblings, and/or Sumia. Could maybe also see a Sully/Stahl duo?
