im inclined to say no
do you have any idea who it would be?
in the eco univrse, time and spirit communications usually only happens when substance abuse is involved such as LSD ( or something similar). Sam didnt take none of those in that scenario
Possible Echo Spoiler:
I think it's John Begay. He's already appeared to Sam as Tsela in the same route and he has a habit of skinriding his descendents.
