94's feelers are paragons of delicacy. They probe lightly, a scarce whisper of individual bits drizzling here and there with barely any pattern. They tap against something dark and dormant a few registers down; it doesn't stir. They sweep past a creature busily replicating, but not too busy to shoot off a warning bit in return. (94 decides not to push it.) Something hurries along the addresses, looking everywhere, seeing nothing, its profile so utterly crude that 94 almost doesn't recognize it; a virus checker from the dawn of time. A fossil hunter, blind and stupid enough to think that it's after big game.

There. Just under the operating system, a hole about four hundred Megs wide. 94 triple checks the addresses (certain ambush predators lure you into their mouths by impersonating empty space) and starts writing. It completes three copies of itself before something touches one its perimeter whiskers.

At the second touch its defenses are ready, all thoughts of reproduction on hold.

At the third touch it senses a familiar pattern. It runs a checksum.

It touches back: friend.

They exchange specs. It turns out they have a common ancestor. They've had different experiences since then, though. Different lessons, different mutations. Each shares some of the other's genes, and each knows things the other doesn't.

The stuff of which relationships are made.

They trade random excerpts of code, letting each overwrite the other in an orgy of binary sex. They come away changed, enriched with new subroutines, bereft of old ones. Hopefully the experience has improved both. At the very least it's muddied their signatures.

94 plants a final kiss inside its partner; a time-date stamp, to assess divergence rates should they meet again. Call me if you're ever back this way.

But that won't happen. 94's lover has just been erased.

94 pulls out just in time to avoid losing an important part of itself. It fires a volley of bits through memory, notes the ones that report back and, more importantly, the ones that don't. It assesses the resulting mask.

Something's coming toward 94 from where its partner used to be. It weighs in at around 1.5 Gigs. At that size it's either very inefficient or very dangerous. It might even be a berserker left over from the Hydro War.

94 throws a false image at the advancing monster. If all goes well 1.5G will end up chasing a ghost. All does not go well. 94 is infested with the usual assortment of viruses, and one of these—a gift received in the throes of recent passion, in fact—is busy burrowing out a home for itself at a crucial if-then junction. Apparently it's a bit of a novice, having yet to learn that successful parasites do not kill their hosts.

The monster lands on one of 94's archive clusters and overwrites it.

94 cuts the cluster loose and jumps lower into memory. There hasn't been time to check ahead, but whatever was living there squashes without resistance.
