I blame... (spoilers)
the last ep, SE EP6, on the writers. Fet should not have taken all day to get to where he could explode the silver bombs. Did time move differently? Did the strigoi attacks slow him down so that it took till nightfall to get in place??
The trap had to wait till nightfall to work I suppose but really... ALL DAY to get to the spot?? Lousy writing of the plot arc for the ep. A line or two about being slowed down or "it's getting late, these strigoi are making us lose daylight" from Fet would have been all that was needed to explain their 12 hour or so trek. Otherwise due to it not being there; it made no sense.
Reminded me of the old Hammer vampire films where no matter what time Van Helsing leaves to stake EP6 the vampire it is always twilight when he arrives!
