Mattheo Riddle.

You were in Theodore's bedroom, your brother, you had asked permission to shower there since your bedroom would be occupied by Pansy and a ravenclaw

You left the bathroom with a towel covering yourself and froze when you saw your roommate lying on the bed

• Mattheo was reading but upon noticing your presence he tilted his head, taking his eyes off of his book and raised his eyebrows *

Are you Theodore's little sister? asks, smiling slightly
