The map showed a lot of demons heading to Sleepy Hollow all at once but then The Hidden One said he can only summon them, one at a time. So that didn't make sense.
The Ghoul was a better monster than that gargoyle. The scarab was interesting but I would think once he gave the scarab to the ghoul, it wouldn't obey him anymore.
Is Abbie a shadowhunter now? The symbol she kept drawing looks like an upside down shadowhunter symbol.
The father stuff was really boring. Last episode Jennie called him a deadbeat but he joined the military so their mom would have healthcare. It doesn't make any sense, other than to try to make him look bad.
