Despite Lex's concerns, Rick ended up performing his job well. It helped tremendously that accompanying him was an incredibly strong monster with almost no intelligence at all.

Moreover, with Toro as a guide, and the awesome might radiating from the invitation, an exception was made and Rick was allowed to enter the Trelop Sacred lands. Moreover, they even promised to help out in delivering the letter to the Poloids.
With his major troubles taken care of, Lex slowly took a backseat and allowed things to progress naturally. With Ash coordinating well with the Phillips family, let alone the tavern, all of Babylon was getting ready for the wedding.
