Even though they didn't meet until they were adults, it didn't take long until Niamh and Seán grew as close to each other as any siblings.
1. You're so cute when you blush. It is the prerogative of any big sister to gently tease her younger brother. Seán is so shy sometimes, and so cute when he blushes. At the same time, he knows she won't let anyone else lay a finger on him.
2. You're always safe with me. As much as she might tease him, Niamh is still proud of her little brother and they have only grown closer in the short time they have known each other. They both know they can rely on each other, come what may.
