Dialogue
"I bring an urgent message from Rhea Opacurius, chief oracle of the Twilight Queen, Azura."

What does this oracle of Azura want? "Best discuss that with Rhea. Too many eyes and ears here. She awaits you at the Cloudy Dregs Inn in Wayrest."

"Hurry to the Cloudy Dregs Inn. Our situation grows perilous, and Azura is anything but patient."
 * Fair enough. I'll meet Rhea in Wayrest.

Trivia

 * Upon being added to the game, Alessio had no clothing, did not have any recorded voice lines, and lacked any hair. These issues were all specifically fixed in the 104 megabyte Patch 2.7.14, along with a capitalization error for items.
