Surely the Jin Blooded can use his ability on the Command Spell. It is a Spell cast on him, after all.
He can either gain 1 fate or spend 2 fate to bind the Spell. It could be bound just to neutralize it (it cannot be discarded in that case, but I don't think we need to discard something that is not a card), or it can be cast on a new target. Here you can have different interpretations:
1) "A new target" means a single new target, so you can choose the Command Spell to affect only one character of your choice (including the one on the Crown)
2) "A new target" means a different configuration of the multiple targets the Spell may have, so you can affect all characters except Jin Blooded.
Well, Reflection does turn the Command Spell into a single-target spell back at its caster.
It's surely true that Reflection can be cast on the Command Spell (it is stated by the Spell itself), but I don't think it is granted that ALL characters except the caster do not suffer the effect. It might also be valid only for the character who cast Reflection, even though it is less probable. As defined, the Command Spell is cast as a single Spell on ALL other characters (check Rulebook page 20), but the problem is that normally a Spell has not more than 1 target. Command Spell and any Hydra Spell duplicates are the exception to the rule, but while Hydra Spell instructs to treat the Spell as if it was cast individually on each character, there isn't such a stipulation for the Command Spell.
Reflection is indeed one of the most poorly worded Spells ever (another is the Hydra Spell). Well, it's not the wording that lacks something, but it's the effect that is too general and undefined. Their infinite options make these Spells neverending sources of problems. The only way to handle such Spells is to realise the "intended use", instead of applying strict word analysis. If you check the words, you won't be able to cast Reflection on Mesmerism, but if you go by the "intended use", then you would be able to do it, as it is a meaningful and thematic effect.
Personally I prefer strict word analysis, as "intended use" is not something that allows setting a dispute during a game. Often the analysis cannot give a final answer, and sees me begging for a clarification (= someone officially entitled to decide which is the way to go).
If a FAQ entry would ever say a final word on Reflection against Command Spell, it should take into consideration Jin Blooded's ability as well.
