In every friendship there are different people. In this case, it's completely true. Aelin- she is the Brutally honest confidant. Reva- she is the Fearless adventurer. Alex- she is the Loyal best friend. Adriel- she is the Wise "mentor". They need each other to survive. And when senior year of high school starts, they need all the help they can get. *** "We have each other, that'll always be enough."
