Compton pulls out two baton like objects. Made of a maglite type flashlight with a couple of gizzmos duct tapped to the sides and where the light bulb would be housed. Standing he extends one of the tubes to Alyx and says, "Here lady, take this and walk over there a few feet.." he asks her, pointing to Alyx's left and then turns and hands Penny the other one that she was already expecting and points to her right, "Over there."
