So Link walks into a Fairy cave, stashes some in a bottle, then just kinda... absorbs another to refill his health. Wait, absorb? That's a little vague. Wouldn't he need to... yeah.
It's horrible. The next time you crack open a bottle and top yourself up in a Zelda game, just think about what you're actually doing, and try and be a little more careful, OK?
Nintendo might be too scared to show you the truth, but now you know.
