Boschwell and the other players are unable to look at what's going on in front of them. The sands are blocking their vision and can't tell what's going on behind the thick sandstorm, but they can hear screeches and roars coming from inside the dust cloud. The thick and gooey blood of the monsters is splattering out the dust cloud and it makes Boschwell and the others are more curious about what's going on inside the dust cloud but they're too scared to get near it.
They think that Trevor can hold Letrax off on his own, but they don't know what's truly happening inside the dust cloud. Trevor is already at his limit and all the buffs that he took a few hours ago are now have expired. Even for someone like Trevor, he can't do much when it comes to dealing with an extraterrestrial monster that thousands fold stronger than him and that alone is enough to tell what's the outcome. Trevor may be winning the fight for now but sooner or later he will lose the battle.
