First thing that came to mind :) But it's not fasciated, it would have been if those two branches would have remained one, like a double, and then add more to widen it. This one is perfectly round below the split and the two new tops are round / non-fasciated as well. I'm pretty sure it's either way not a genetic trait but an indirect result of the weird morphology during the recovery after/during the difficult germination and seedling fase.
Walked in the kitchen while my wife was cooking and thought I caught a glimpse of SSH/Amnesia haze smell, turned out to be bay leaf, package says, "spicy and woodish". My bay leaf has a hint of mint too, so it's different, but cooked combined with beef it smelled surprisingly haze. Makes me wonder, does the "AC" you got, SSH/Amnesia haze x GSC (thin mint?) smell like bay leaf?
