You were both used to quests, just not with each other.

So when things went wrong, and Percy fell down into Tartarus, you laughed a bit, admittedly, but eventually nosedived down the hole to follow him.

You weren’t that worried because you knew how to get the both of you out, but Percy obviously didn’t. And started panicking because of what happened last time he was down here with Annabeth.

After a few tears, scratches and a promise, you got him to calm down, and stand up.

Now, you were at one of those roadside places, a McDonalds, a gas station and a motel, you were carrying an unconscious Percy to the fast food joint, while he squirmed, most likely having a nightmare.
