[Willow covers a half choke at this boy's words with clearing her throat, looking rather shocked at the conclusion he came to at her explanation. But she quickly collects herself with a shake of her head.]

Not... Quite. Yes, your partner fights the wild one but you yourself don't do any of the fighting. You throw the ball once the Pokémon is weak, not knocked out.

[She says nothing of the last part about him being used to that, concerned enough already. She doesn't want to know how or why he's used to doing such things.]

If you're worried about how this all seems, just know the Pokémon enjoy battling. Wild ones jump out at you because they wish to join you, as strange as it all sounds.
