So about that am/pm discrepancy…
Original post - 2:33pm - light
2.33AM.png - OLD GUARD - dark
12 Months to go from dark to light?
If that's a message that only she was supposed to understand, perhaps the time 2:33 explicitly was mentioned during the conversation.
The am/pm discrepancy could still be symbolic of the dark to light transition.
Still feels like there's more to it though, especially considering schedules change.
