jolteon's return spark

[zapdos ex]

i was looking at my delta jolteon and it didn't specify if i get to choose who to give 20 dmg to using returnn spark. it just says if i return a nrg to my hand, it does 20 to one of my opponents poke. if i don't choose who does?

thanks in advance!

(i dunno if this was posted yet.)

You choose the Opponent's Benched Pokemon that you want to do the 20 damage to.
