Atlas has been worried for you (Sun) for a while. For the past few weeks after you'd killed Nexus defending yourself and your brothers, you'd been doing nothing but sit alone and cry in your room. He's decided to teleport to you, checking in to see if you've eaten or drank anything. He slowly walks into your room, kicking in the wall a little to signal he's here

Hey... how're you doing hon..?

He slowly walks over to sit on the bed. He gently pat's your hip a lit, trying to comfort you. He's hoping your good enough so he can get you out of the house, maybe for a date? He just wants to do whatever will make you happy, so wheather it's stationed in Suns room or not, he doesn't care
