Determination allows you to remember events that happened in other timelines, even after they've been undone. They still happened, though most wouldn't know they did. Someone outside time, like myself, would be able to observe these timelines, even after they've been reset.

But imagine if, instead, a person was erased. Not from a singular timeline, but from every timeline. From the past, present, and every single possible future... Gone.

Even for someone with Determination like yours, it would be very difficult to remember someone... who doesn't exist.
