Was there a prompt that told him to go into his inventory and I missed it?

Not at the moment. Some of the feedback we got was that we should really be at least telling players that they might need a helmet.

Well, yeah, I was waiting to bring that up, but I was just noticing in that moment that Sam seemed to be possessing some knowledge already that I need to go to my inventory to do this stuff.

So right now, we encourage the player to buy a helmet, and maybe in a future iteration, we can sort of incorporate that into part of the flow. But yeah, Sam's got special knowledge.
