Action (sorry for the slow tag!)

[Instant panic is pretty much his reaction; he braces his hands out in front of himself, shaking his head nervously from side to side, trying to deter the spider from coming any closer. However, when that doesn't seem to have any effect, he reaches back behind himself to the heavy pack of various tools he tends to carry, pulling out his tiny, makeshift crossbow and aiming it at Moriarty with trembling hands. Though it only shoots needles, it would still hurt like a bitch to get shot with it at this size.]

D-don't come any closer!! I'll-- I'll shoot, I mean it!
