The Soldier feels a flash of irritation as his shot goes wild, the Target thrown away by the secondary priority. It's not an immediate kill shot, he can tell just by looking at the bloom of red blood spreading over the blonde woman's clothing (something buzzes in his head, like he should know her, that he's seen her before...) and with medical attention she could live -- however medical support is limited here, he is content she while die soon enough.

His gaze flashes to the initial Target again but there is now a limited timeframe to work with. No silencer was available to him, meaning his single shot will have been heard through the mall. It's reasonable to assess that other tributes will come to investigate what happened in short time.

He needs to move.

Springing up from his hiding place the Soldier fires again at the two and doesn't wait to see if the shot injures, kills or misses completely as he takes off across the upper floor, in seconds out of sight of the two women.
