She can hear the radio just fine, but his voice cuts out completely.
Billy is one of few openly gay male Marvel characters.
Rio also told Agatha that he wasnt her son in Episode 4.
Still, theres no telling what hes doing on the Witches Road or why he sought out Agathas help.
Episode 6:Familiar By Thy Side
Episode 6 ofAgatha All Alongtook viewers deeper into Billys backstory.
The first word out of Billy Maximoff/Kaplans mouth when he came to was Tommy!
He never remembered his life before the accident, despite fooling his parents into thinking he did.
His telepathy manifested at the hospital when he could hear his parents inner thoughts.
A shot of Locke wearing clothes very similar to an outfit young William Billy Maximoff wore inWandaVision.
The below character poster also depicts the costume.
Turns out, this shot is from Episode 5, during the trial, shortly before his Wiccan reveal.
In the comics, Wanda created her twin sons from two lost souls that Mephisto lent her.
Wiccan became a young avenger alongside Kate Bishop and Cassie Lang.
in regard to Teen.
They say that nobody really knows what happened to him, Jennifer says.
They say he might be dead.
Others say he might be a demon or an agent of Mephisto.
But hey, thats what happens when you have Agatha Harkness as your mom.
I doubt shed even recognize her own son if he showed up on your doorstep.
But, the clue also called back to Rio Vidals self-described black heart that beats for Agatha.
Well, interestingly enough, Blackheart is a character in the Marvel Comics.
In fact, he is the son of Mephisto.
If Rio is Blackheart, it makes sense she might come looking for Wandas son.
However, Teen himself could also be Blackheart as well.
Still, more hints arrived at the end of the shows fourth episode as to Teens true identity.
