Lin didn't understand what had happened exactly.
Confusion being amplified by the speed with which the situation had changed from crisis to... something different that seemed equally urgent.
She got distracted observing the exchange to the point where she didn't notice the mutant approaching her from the right flank.
The creature exploiting the moment of inattention to close a distance that normally would've already obtained Lin's attention.
It wasn't particularly dangerous despite everything…
She would've easily eliminated it if it got closer. Her reflexes being sufficient to respond before any Silver-rank threat materialized into real damage.
But she didn't get the opportunity to demonstrate it because someone eliminated it first.
Intervention being so fast the mutant fell before Lin could appropriately react. A corpse hitting ground while Lin was still turning toward the threat that no longer existed.
