Playing both sides

When Rudra asked Amelia to bring in the chalice. He also instructed her to send two guild members to the church of light and meet Cardinal Lee . 

Rudra gave a message for Cardinal Lee that he was currently stalling members of the same faction as the blood merchant in his guild hall , and that he should instantly provide reinforcement. 

Cardinal Lee had worked with Rudra before , bestowing on him the title of Emmisary of Church , hence his word carried weight as he instantly deployed the church's paladins as well as came himself to the guild headquarters to detain those in question. 

When Megan and Gary went out of the guild hall with the chalice in hand , they were naturally shocked to see a platoon of paladins standing. Their natural fear took the better of them as they reacted in a way only guilty people would. 

Being detained and dragged away to the church for questioning , they were naturally spewing insults at Rudra for framing them.
