"Maybe follow 20' behind?" suggests Polly, and heads off into the dark cavern, which opens out to about 8'wide and 8' high.
There's a 'thwop' noise ahead as Ruehar enters the darkness. It takes a few seconds for his eyes to adjust to see that Polly is using her sling to assail a crouching, vaguely avian creature with bony hooks for hands. Its vulture-like head turns towards Polly, eyes wide, though whether in surprise or indignation at having been interrupted during seeing to its bodily functions is impossible to read.

Polly scores a second hit in the creature's avian eye before Ruehar sticks two arrows into its body and then Polly cracks it with another silver coated war bullet.
The creature collapses, presumably dead. Polly approaches cautiously, pulling out her short sword and pokes it in the eye, confirming it is indeed dead.
With a brief search, Polly recovers all but one of her war bullets, Ruehar recovers one arrow and the cave creature, now can be seen as being about 8' tall
{OOC: Large}, has no discernible treasure.
The Halfling Outrider nods, swaps sword for sling and presses on. The cave opens out to 10' wide by 12' high and slopes steadily downwards.
After another 50' travel the cave opens into a roughly off-centre oval, 45'x70'.
Two more of the cave creatures lay a few feet apart, asleep, on the opposite wall immediate in front of Polly.
The large, prone creatures are obviously surprised. What will you (both) do?
======
Surprise:
Polly: d10=3+4(Talents)+1(GH)=8
Cave creature (CC): d10=4-6(Halfling racial+kit)=-2
8-(-2)=10 segments of surprise.
Readied missile fire ROF1: segments 1, 4, 7, 10..
Readied missile fire ROF2: segments 1, 3, 5, 7, 9..
Movement by segment is doubled.
Normally 1 round for eyes to adjust (daylight to infravision) so going to say Ruehar loses 5 segments of surprise.
Polly get 4 sling attacks & Ruehar gets 3 arrow attacks
Segments:
1) Polly hits (7 dam)
4) Polly Mulligans a fumble into a hit (19 dam penetration)
6) Ruehar hits (6 dam)
7) Polly fumbles but her sling makes is saving throw
Have done the housekeeping for arrows.
8 ) Ruehar hits (6 dam)
10) Ruehar misses; Polly hits (6 dam) ==> CC1 dies.
CC2 & CC3 are surprised (asleep and prone). Choices:
Automatic hit with melee weapon IF you both make successful MS rolls to approach.
Missile fire is +5 hit until the end of surprise (already rolled but not stating how long yet) and RoF as above.
Run away like frightened little sheep.
