He will seat himself next to a dying person and offer a cigarette. if they decline he just used his own, if they accept then he lights both for them, he doesnt engage in fights and is silent all the time ALWAYS SILENT. SCP-4999 has not been seen to engage in any other activity or behavior, and demanifests immediately upon the subject's death. The subject's cigarette, however, will remain, providing the onlyevidence of SCP-4999's presence. NEVER TALKS, I cant stress that enough.
