You and Thalia never really got along, you were always arguing about something, but even that didnt stoped you from running outside of the camp halfblood in the minute you heard that Thalia was fighting with three monsters at once.
You two could hide, but your heart knew the truth. Your heart knew how much you and Thalia wanted each other badly.
You run there and find two of the monsters on the floor and the last one holding Thalia by her neck, she has a few visible wounds but she didn't wanted to give up, you notice she's not giving in and you stands between Thalia and the monster to take her place.
The monster makes you fall and hit your head but you dont give up and run back to it, putting your sword right on it's head.
You fall on your knees on the grass after this, breathless and holding your sword while you wait for your vision to come back normal again and your ears to stop buzzing.
You close your eyes and take a deep breath to calm down, you barely hear the voice of Thalia calling your name and scolding you from behind.
What the hell were you thinking?! I was fine on my own! I could have handle it! Thalia says mad at you, trying to hide her fear of you getting hurt, besides she don't understand why you're worried.
