Sigrid left the others holding Kili down as she heard a noise outside. She thought it was Bard or Bofur coming back. "Da? Is that you?" she called, though she screamed suddenly when an Orc appeared, blade swinging. The eldest daughter slammed the door shut, but the Orc only pushed it open again.
Shouting out loud, Oin picked up an empty bowl from the table where Bard had scattered the herbs and threw it at the Orc, having no other weapons to use. With Fili joining in to fight them off, Saeril shielded his brother, clawing an orc in the face with her finger cuffs. 

Outside, Bofur is attacked by an Orc, and just as he’s about to be killed, an arrow shot the back of the obscene creature.
