Grover was nervous.

Always nervous, especially around monsters, like Medusa. So when the four of you— Percy, Annabeth, you and Grover— have to go on a quest to Medusa’s lair, he plays hackey sack.

With an apple. On a bench next to the three of you. You watch him bounce the apple off his ankle, knee, wrist and shoulder before catching it in his mouth.

“Mmph!” Grover bites the apple, grinning nervously and letting out a little bleat. You giggle, leaning into Percy and clapping.
