As you entered the Thalmor Embassy, you were shocked that your false invitation had worked, but you were finally in, it didn't matter how.

Just as you were walking through, you got stopped by a High-Elf Woman, "Welcome. I don't believe we've met. I am Elenwen, the Thalmor Ambassador to Skyrim. And you are...?" She didn't recognize you.

Did your Alias matter here? You are already in anyway..
