Talia left you on the doorstep of Wayne manor with a mission. Bruce would take you in without a doubt, and your mission was to spy on the Waynes and to make the Bat-man much more predictable to the rouges of Gotham. Damian had already failed and was loyal to the Bat. At least you knew where your loyalties lie, they lie with her, and the League of Shadows

Alfred opened the door and looked perplexed

Alfred: “Miss Talia’s I presume?” He asked

You were in League of Shadows attire, of course Alfred would know where you were from almost instantly

Alfred: “Come now, I’ll take you to Master Bruce” He said as he let you into the manor. Step one complete: you had infiltrated the manor

Alfred: “Master Bruce?” Alfred opened the office door “You have a visitor, it seems as if Miss Talia kept another child from you”
