Jennifer Maas TV Business Writer SPOILER ALERT: This article contains spoilers for Episode 6 of “Gen V,” titled “Jumanji” now streaming on Amazon’s Prime Video. This week’s “Gen V” came with a pleasant surprise for fans — and we’re not even talking about Thursday’s Season 2 renewal news that hit just before the episode arrived. The installment featured the much-teased cameo of Jensen Ackles’ “The Boys” supe Soldier Boy, who appears to Marie (Jaz Sinclair), Andre (Chance Perdomo) and Jordan (Derek Luh/London Thor) as they travel through Cate’s (Maddie Phillips) fractured mind while she’s breaking down from doing too much brain-wiping/un-wiping of her friends on behalf of Dean Shetty (Shelley Conn).
