With the stranger directly below him, the creature should strike right away but after his long nap he seems a bit more curious than usual.  The signals from the scanner are messing with his sonar, making that sense of his basically useless.  Still, his sense of smell is working perfectly fine.  He lowers one of his arms towards her, behind her back, and is ready to touch her, so he can better "investigate" his new friend.  Of course she moves just as he is ready to do so, moving closer towards his nest.  The cavern is linear, sloping gradually downward, the floor covered in a thin residue left by "him", which she does not seem to slow her down.  Quietly he descends to the floor and begins to follow her, only a few feet behind.  His scent is masked in the cave, as the odor only increases as one nears the nest.  With his tentacles spread out, all poised to intercept his guest, he follows, careful not to alert her.  Soon enough she arrives at the lowest level of the cavern, his nest.  In front of her, the ground seems to submerge a few feet into a strange fluid and the scent is particularly strong here.  He sits, waiting to see how she likes her new home,  eager in anticipation.
