Ouch, unfortunately with nameless your chosen choices are hard baked into your save so you would have to make a new game to actually undo it. Reloading a save or deleting data only makes him comment on what you did as he remembers your choice, as you know. So unfortunately there is no way to avoid it just make sure to choose wisely.
I’m not sure if this will work for you, but it did for me—and it’s actually not that complicated. I messed up my choices with Nameless a long time ago, so I experimented and figured out a way to kind of “reset” him. It may require restarting though.
Basically, when you go to a file manager > android > data > com.r3nn.ld > file > saves, you will find a file named “persistent”. This file is the one that lets Nameless remember everything across saves.
(It doesn’t matter which save you’re on—as long as this file which you've made a choice you didn't like exists, Nameless will carry memories.)
Here’s what I remember I did:
1. Go to your saves and copy your important saves (every save should be BEFORE making the choice with nameless), ESPECIALLY your latest clean save—again make sure it's a save BEFORE making the choice you want to avoid—and paste/back it up somewhere safe (like Downloads).
2. Uninstall the game and delete all data completely.
3. Reinstall the game, then paste your saved clean files back into the save folder so you don’t have to restart everything. (Reminder: before pasting, there's a first save file in page 1 whenever you reinstall the game, you have to delete that if you want to paste in page 1 with the same name "1-1-LT1" save, otherwise an overwrite notification might occur)
4. Now that everything’s clean, a new persistent file should be there if I remember correctly, if not, play the game until you meet Nameless (try without picking any choice first) and check (if it's still not there, be careful and pick the choice you want on your first reply with him, then save) and check again, it should appear now, copy and save that new persistent file somewhere safe and accessible—it should be free of Nameless’s memory.
From now on, just go to your latest save and play the game as usual. If you make a choice involving Nameless that you didn't like:
Go back to a save BEFORE making that choice
Go to file manager and delete the persistent file that was "tainted"
Replace it with your clean backup from Downloads (just copy it so you can use it again and doesn't have to uninstall the game)
Open the game and load a save from before the choice was made—Nameless won’t remember anything
From here on, you can safely use that backup persistent file anytime you need to reset Nameless after making a choice with him that you didn’t like.
It may look complicated but it's not, trust me. This way, YOU are the one taking control of nameless's memories. just always have a backup of that clean persistent file.
I hope this helps.
