Hi guys! How are you doing?

I need some help because I've been trying things for a couple of hours and got no results at all. What I want is pretty simple but can't figure out how to do it, so I thought maybe you could show a beginner some love!

You surely know about the Companions Purity quest for Farkas and Vilkas, right? The problem is that I only get all the other radiant quests from them but the one I really want (I've been playing radiant quests for hours and they always offer the same ones).

I wrote in the console "help CR13" and found the DIAL StartQuestTopic tagged as E2868 (I think) which triggers the Purity quest, and what I want to do is this dialogue option to show up in the conversation with Farkas and Vilkas so I can finally trigger that quest and complete it by finally curing them.

I found this same dialogue option in TES5EDIT typing the code in the EditorID field, tried a couple of things, launched Skyrim again and found that any of it had the desired effect...

This would me an awesome mod because almost everyone is having the same issue with this quest, and a mod that simply makes that conversation topic appear would be great for every living soul in Tamriel,

I'm totally lost, would you be so kind to throw me a hand? How could I do what I just explained? Thanks in advance guys!
