To avoid potential confusion, some clarification:

Yes, Alpha is in two places at once. For the majority of my post she is in her containment area, and towards the end she appears in the Auditorium. (Please check the next paragraph before posting a reaction to her appearance.) She will do this often, possibly even add a third in the future. 

Only Puppeteer/Alex can see/hear/speak with Alpha at the moment. Although a few, such as Alma and Daniel, will be able to sense her presence very close by if their players would like them to. Their option. If you'd like your character to sense her nearby, just run it by me real quick. (In the OOC here, in PMs, on the Discord, in a Discord DM--however you're comfortable reaching out to me, I have no preference.)
