Whoa!! The protection wards Eden has been casting on Isaac are still paying off.

ISAAC: "Hi, Blair." He stares ahead and shoves right past her, breaking through the covenhouse's wards with the power of Eden's protection wards covering him. Blue tendrils of light flow off of him trailing away as he runs into the house and up the stairs. Riley, Akiva and Quinn stare in shock at him. Akiva looks frazzled and holds a comically large coffee mug. BLAIR: "Isaac, wait!!" RILEY: "Who is that? How did he get past the wards?" AKIVA: "It's too early for this kind of excitement." QUINN: "Akiva, it's past noon." Blair stares after Isaac in utter shock, seeing the blue light that Riley and Quinn can't. She realizes what Eden has done. Meanwhile, Isaac makes his way up one of the tower spiral staircases.
