Marco, Callum, Rose, and OPEN
It hadn't occurred to Marco to call out for help from those still at the station - he was still meeting people and didn't know who would be ready to run out into danger and who would want or need to stay behind for those that may be shipped back to the station for further help.
As he came to the source of the issues he paused momentarily to assess the situation. Running, screaming, other sounds, and the scent of fear, adrenaline, and blood all filtering through his olfactory system. He followed the blood and as that scent mixed with wolf he found a man on the floor already being helped by Rose, good, but why wasn't he already healing himself? Under the assumption that wolves from all walks of life, and other lycans, naturally healed - a bullet wouldn't be an issue. Unless it was silver.
The idea of silver weapons being used made Marco's hair finally stand on end - hunters, it was the only possible explanation. Why here and now? More importantly who were they coming for or was it just an all out slaughter? He forced the thoughts from his mind and finished the jog towards Rose, dropping his own pre-made duffle as he crouched, "There's got to be silver, we need to get it out," Marco offered, under the assumption that a silver bullet being lodged within the man could be the only reason why he wasn't already back on his feet.
