Alexey can catch her before she had a chance to let them know she was hiding over there
Cercelee bristled at Firefly’s taunts at Alexey. This was no way to treat a pack member who had returned! Cercelee was aware Firefly (and Haku and probably Svara) did many things in her absence that she would not fully approve of and got away with it, simply because Cercelee never learned of such actions. Firefly did not know Cercelee was listening in, and she would be getting a lecture on border greeting etiquette, even if Alexey was not technically a newcomer and they were not patrolling the borders. Perhaps Firefly had been justified in the beginning, she was allowed an outlet to her emotions, but not the girl was just toying with her friend.
And what would Alexey think? Cercelee raised to her feet, shaking out the snow that had collected on her coat. This had gone on too long, it was time to make her presence know, she was ready to step out.
