After bidding farewell to Howard’s mother — and beloved actress Carol Ann Susi — last month, The Big Bang Theory is adding another branch to the Wolowitz family tree.

Matt Bennett, best known for his starring role in Nickelodeon’s Victorious, has been cast as Josh, the younger half-brother of Simon Helberg’s character. Josh will show up unexpectedly on Howard’s doorstep in the April 9 episode (CBS, 8/7c), titled “The Fortification Implementation,” TVLine has learned.

Josh’s arrival is likely to strike a nerve with Howard, who’s never even mentioned his half-brother in the series’ eight-season run; the two share a father who famously abandoned him when he was still young.

In addition to Victorious, Bennett’s TV credits include roles in Nickelodeon’s iCarly and Sam & Cat.
