His fate remains unclear - he may have been killed in the catastrophe or separated from them during the event.

However, he later kidnaps Kai, shattering the trust that had developed. His motivations remain ambiguous - whether for leverage, ransom, or other purposes is never fully explained.

Foreshadowing: The stranger's arrival is presented hopefully, but the narrative hints at the moral complexities of survival where trust becomes dangerous.
