Specimens: 2 (coded green)
Addendum: The two collected specimens are the only survivors of at least seven observed cases. Other specimens were destroyed during attempts to capture them. From (as yet) unverified observation, it appears that there may be as many as four distinct subgroups within the R3’s.
R3/A: These reanimates appear to be capable of running over/around obstacles, including random objects, hallways, stairs, etc., as long as the obstacles are stationary. They did not, however, display competence in avoiding obstacles introduced into their paths. There appears to be some disconnect with perception and reaction time.
R3/B: These reanimates were not only able to run over/around obstacles, but they demonstrated a marked ability to avoid additional obstacles introduced at varying speeds. NOTE: One such specimen avoided a rock thrown at its head and attempted to leap over a shopping cart shoved at it by one of the soldiers in our detail. It failed in its attempt, however, and was subsequently put down by the soldier.
R3/C: One observed specimen presented the greatest number of radical behavioral changes. It was able to negotiate obstacles and avoid many of the objects thrown at it or tossed into its path; and it demonstrated a shocking tendency to use simple tools. At various times during a running fight, it used rocks and sticks as clubs and even threw (ineffectually) a stone at one of the soldiers.
R3/D: It is this specimen that most disturbs me. In the absence of formal study, this reanimate appeared to be able to grasp certain concepts, particularly stealth and subterfuge. It appeared to hide behind an overturned car and wait until a soldier walked past, at which point it attacked the soldier, inflicting a serious bite. While other soldiers pursued it, the specimen twice hid, and twice changed its gait to imitate the slow walkers. As a result, two additional soldiers received bites. Though both wounds were superficial, the infection did take hold. In light of secondhand observation only and no formal investigation, I hesitate to rate this subspecies according to the Seldon Scale. However, Dr. Han and Maj. Dietrich both suggested that it would probably rate in the high 8’s. If they are correct, and if this is anything more than a regional fluke, this is a potential disaster.
NOTE D.1: All three of the soldiers who were bitten expired within seventy-two hours.
NOTE D.2: Two of the three soldiers reanimated.
NOTE D.3: One of the reanimated soldiers (Lance Corporal Herschel Cohen) displayed all the behavior patterns of the classic slow walker.
NOTE D.4: One of the reanimated soldiers (Private Zachery Bloom) displayed characteristics typical of the R2’s.
NOTE D.5: Staff Sergeant Linda Czerkowski did not reanimate, even though she was observed continuously for forty-eight hours. Samples of her blood, tissue, and brain matter were collected and are in dry ice, bin #119.
Conclusions:
I think we can put to rest the debate as to whether the Reaper pathogen has mutated.
We have been able to isolate fairly pure examples of the parasite, and we can begin studying them once we get back to Sanctuary.
The sequencer at Hope 1 is on the fritz again, so we have been unable to sequence the DNA, either of the parasite or these new mutations; however, it seems clear that Reaper is continuing to mutate. There is no way at this point to know how many new strains of the disease are active within the reanimate population.
I would like to again strongly urge the lifting of the communication ban. Without open discussions with colonies of survivors, we will never be able to amass a reliable body of information. We simply do not know enough, and it is imperative that we establish the location and spread of new Reaper strains.
