I took myron as a companion and i dont like him.He svcks at fighting and i wanna travel with sulik but i dont wanna kill him so how do i get rid of him?

Tell him to get lost, that you don't want him around.

With Moro.... I err mean Myron you need to be a little more forceful than most.

As Styles said he can be told to leave your party verally; but I prefer to sell him off to Metzger or Vault City myself... Although some swear body part removal in S.A.D.

Thanks.Ill sell im to slavery then.I deserves it for killing about 100 people testing jet and then adicting a lot more.

Myself, I'd leave him someplace (that I could come back to). Myron has a lot of dialog, and can make the more expensive drugs; Also Marcus never stops messing with him.

** Lore-wise he gets his karmic reward not long afterward anyway.

** Though no good for combat, he is a quest NPC (if you haven't done it yet); and similar to Vic, he has a high skill ~In his case Science.

Does that mean that if i tell him to wait the game will give me a follower slot?

IIRC... (its been a long time since I had an over crowded party), I think Yes. I think that telling an NPC to wait removes them from your party. Have you tried?

The only party members that you cannot ask to wait are Dogmeat and Miria (the wife).

Be aware that changes in your character's reputation (due to past actions) might cause certain NPCs to decide not to join up again when you ask them.
