At that moment, someone knocked on the door so thinking it was Amanda or maybe Nathan, and since the gate was already opened he just told them to come in.
"Hey Amanda, is Nathan here already?" Arnold asked without even looking towards the gate as he was busy tweaking his gears a bit and he also heard someone walking in heels so he was sure it wasn't Nathan... until and unless Nathan had developed a weird personality.
"Who's Amanda?" A familiar feminine voice echoed in his ears. it was a voice he hadn't heard in years.
"Nicole!?" He was both shocked and surprised to see his little sister standing next to him.
"Hello, brother..." Nicole tried to give him a cheerful smile like she always did when she was a teenager, "It's been long hasn't it?"
Before Arnold could react, another voice came from next to Nicole, "Ahm... before you both do something weird, just remember I'm here as well?"
