There were enough training sequences featured in Heads Up that even the Rocky movies were getting jealous. If Rick teaching Ron how to shoot wasnt enough, we find Rosita teaching some novices how to wield a machete and cut through bone. Whilst seeing Eugene doing this thing is always great, the biggest WTF moment about this whole thing was likely that we actually got to see Rosita. Seriously, where has she been for the majority of the previous six episodes?!
