Bugs
After completing the quest Emily will remain outside the casino and you can talk to her to learn about the first attempt on hacking Mr. House's network. A 35 speech level dialogue option eventually becomes available that will remain in the dialogue list even after granting the player the reward for selecting (experience, completion of speech towards challenges). This allows the player to get credit for completing speech challenges (the experience points for completing the speech option is only given once however). Note that ending the conversion will block any further communication (and thus exploitation) although Emily will remain in front of the Lucky 38. (360)
