Huh, you're actually serious? I thought you had to be being sarcastic.
I will go further than Grey Wolf, and say that I will be amazed if there is ever an indication that dumping the weapons was the wrong decision. (There may, though I doubt even that, be some on-panel point at which having the weapons would be useful, but it will remain unambiguous that out of the valley where Andi trapped them without the weapons is superior to still trapped in the valley with the weapons, and that that was in fact the choice on offer.)
