I mean these guys will find that she's not in her room and find her in the bedroom and then, they will most certainly force-feed her the poison.
So, if she cud fire a gun before, she can do so now to protect her life.
Only thing is she is in extreme fatigue, hope she can walk over to whatever cabinet the gun collection is and pick one.
If she can walk from that horrid room to her bedroom, she can walk to a cabinet and get that gun that cud save her life.
The trio are now seriously gunning for her, no pun intended.
She cud keep them talking until Loha arrive or Shekhar arrives with Laali.
She cud at least lock the door from the inside!!!
