I am somewhat disappointed that Mia's story didn't continue in the direction it was made to look like it would honestly, even if it wasn't too unexpected. However it is consistent with the character I believe, since it was pretty weird how okay Mia was with Dexter being the (fake) Dark Passenger that killed random innocent people.
I guess that's why I thought she might be testing Dexter's morals lol, until she found her new target ๐ฅบ
But good on the show for at least not resorting to its own ol' tropes of finding a new love interest that would have to disappear after some time.
I did think she was going to suspect Dexter at the end there though, maybe he got lucky and got out scot-free \o/
... but probably not...
And Dexter also still has to make his presentation ๐
