my Fatalii OW looks very similar with narrow leaves. i'm guessing from either the cut back or low light levels inside.
dont count out a chin x fructensen cross had a few tobascos with triple forks last year, the longer less round leaves makes me think that it could be an annum cross though i guess flowers might give you further clues before the pods come,,
Hoping to see pods soon.
BTW it is a reaper, from Tex16
