How to tell Mercer Frey to kindly buzz off

the-elder-scrolls-v-skyrim

At a point in the Thieve's Guild questline, Mercer Frey accompanies you to a dungeon. He has no dialogue other than one unimportant option, so you cannot ask him to stop following you. After several tries, I decided that the dungeon included in the quest is too hard to clear, so I'd like to level up before continuing. However, since Mercer won't stop following me, he continues to screw up my play style (as a sneak Illusion-type character), alerting people of my presence by opening doors that I've closed, standing in line-of-sight, etc.

He's very annoying. Without the aid of a mod, is there a console command or other way to tell him to buzz off while not breaking the quest when I chose to return to it?

I guess you are on the "Speaking With Silence" quest.If it is the quest ID will be TG05 if not you can simply find your quest on the UESP and use its ID number.

You can reset the quest to it's initial stage ("meet Mercer Frey outside Snow Veil Sanctum") using

   setstage <quest id> <stage value>

in your case

   setstage TG05 0

or 

   resetquest TG05

This will reset your progress,quest items and followers linked to this quest/dungeon.

Use 

  prid 00022651

to select Mercer,then

  setunconscious 1

to turn off his AI,he should just vegetate in the place you left him until you turn on his brain with 

  setunconscious 0

Haven't tested this so I'm not sure what can go wrong.

As it turns out Mercer Frey will still teleport to your location(in attempt to follow you) if you go too far,however might be used in different scenario.

You can also try with set playerfollowercount to 0.Or using Disable then Enable on him,similar with Kill and Revive...But try them only as last resort since there is so much things that can go wrong with this commands(in regards to your quest).
