"How you're here?"
"How am I here? It's a long story." Aditya replied with a smile.
"But it all starts with a prisoner named Silas." Hearing the name, Felix widened his eyes.
Obviously, he knows who Silas is. Originally, Felix planned to frame Silas. The plan was to make the Istarin Emperor believe that Silas was responsible for the explosion at the marketplace. This whole explosion was purposely done to divert Aditya's attention and make him believe that Silas was behind this. This was part of their original plan, which they had to change when Felix learned that Aditya didn't take the bait.
"You see, Silas's men accidentally stumbled upon this place. They saw you leaving this place with your Homunculus."
