K9 and OPEN
K9 trundled his way from the Doctors and Harry's location and through into the 'fog', taking up a defensive position at the perimeter of the cave. His 'ears' spun around as he scanned the area, picking up any minute sound - which included Jake and Neytiri's words.
The robot dog's readings came back and it revealed several lifesigns all from different directions but heading towards their location.
"Alert, multiple lifesigns detected on route to our current location," K9 announced over the link to the Doctor's phone. "They are possibly hostile."
"Yes, yes.. well that was to be expected... Bit busy at the moment K9, I'm sure you're quite capable of handling it," the Doctor's - the younger version - exasperated voice came over the communication.
"Affirmative. Sending emergency transmission..." K9 tapped into the main communication system that linked everyone's phones and relayed a call for assistance.
