Honesty I think this is the best argument.
On the topic of the deadeye spren now being the unoathed, do we think that this happens if BAM doesn’t get freed?
I’m not sure we totally know why Maya started healing yet. Was it because of the crack in BAM’s prison? (Side note: how’d that get there?? Maybe cultivation? ) Or does it have to do with Adolin embodying the values of another shard?
Valor is defined, by google , as “great courage in the face of danger, especially in battle”
That perfectly describes what happens in the Azish storyline.
That describes the Notum attack on RoW, the Tower, the mismatched duel, etc. Granted, you can make the argument for all soldiers and indeed valor would be present.
Do I think Valor is hiding in the Fourth moon fragments? Honestly, no. Valor would have had to be there prior to Honor and Cultivation. Odium wouldn’t come for a while yet. What would have driven Valor to hide?
