Following the arrival of Manifest alum Melissa Roxburgh as Colter’s sister, none other than Jensen Ackles of Supernatural and The Boys will turn up as Colter’s brother.
I doubt that Tracker will add Colter’s brother in the penultimate episode of Season 1 and then immediately kill him off.
One brother being serious and trying to get something done, while the other – played by Jensen Ackles – goofs off and messes with them?
Also, if the Jensen Ackles casting news put you in the mood for some Supernatural, you can find all fifteen seasons of that show streaming via Netflix subscription now.
