"Spy is such an ugly word, chica. I prefer select viewing or making new friends." Even if it was absolutely spying. Sombra knew what she did and what she could do. She was hardly ashamed of it.
"Home was hard? Not so much fun like it is here?" If you could call it fun. Sombra did to an extent. She knew the levels of danger and wouldn't put innocents in the path of it. As for herself? She knew better than to get herself killed, but she would never turn down causing some chaos.
