Oh, nice! Yeah, the actor of Robbie Reyes does a really good job, to me.
Really? I'll most likely have to agree with @Iliara_Mustardtop that Season 3 with "It"/AKA Grant Ward was a pretty creepy and intense season, though I am going to have to say Season 4 was very creepy as far as the LMDs (if, @Iliara_Mustardtop, you've gotten to that part yet). We're watching the newest episode of Season 5. And that season is probably one of the creepiest, but I'm not sure if you guys got to that part yet.
I will warn you: When you see Season 5, see some key episodes of Season 3 first. It is totally epic and flows perfectly in the storyline. OMGoodness!
