Ellie approached Kan from behind as he remained engrossed in deciphering the information displayed on the system screen. Kan's sudden awareness of her presence made him turn abruptly, initially startled but then breaking into a relieved smile.

"Hey babe?" Kan greeted, his smile masking the panic and shock that had momentarily gripped him upon her unexpected arrival.
