Voyage to Vulnerability

Describe a situation where Kylo Ren shows a deep-seated vulnerability.

Kylo Ren often wears a mask, both literally and figuratively, but every character has a vulnerability. Script a situation where his emotional barriers crumble. Consider how this would manifest, what emotional triggers could lead to it, and how these unseen aspects mould his character. This task evokes empathy and brings to light unseen facets of even seemingly rigid characters.
