each number is a corresponding letter in the alphabet. For example: the letter A is 1, B is 2, etc...etc...etc

*Ren POV

"10 rounds left in Stormflower" thought Ren to himself as he downed another Beowulf.

"15 seconds approximately until I have to reload"

"8 Grimm left in this pack"

"14 seconds until Nora gets here"

*Nora POV

"3 seconds until impact"

"5 Beowolves surrounding Renny" Nora thought.

"14 Beowolves closing in from the East, but there's someone I can call"

"1 man for the Job" Nora thought with a sadistic smile on her face.

If you want to know who the man was, figure out what letter the numbers correspond to.
