I completed all his missions and he tells me to follow him to that secret passage thing that leads to the Thieves Guild. However, he stays at his stand in the main market area in Riften. I don’t really care about joining the Thieves Guild, but there is a mission where you have to sell something to Delvin Mallory.However, he won’t talk to me until Brynjolf shows up. Please help!
He won’t go with you. You need to go through the rat ways yourself, and he should be there once you make it through.
its a glitch
but luckily there is a solution
