Read carefully. The scene is ... wait for it ... IN HEAVEN! Are you of a mind that purgatory is in Heaven? God forbid such error!
I guess we have to choose which Catholic to believe. I’ve heard there’s fire, no fire, happens before entering Heaven, happens over a long time or just a few minutes; that it is only venal sins, not sins but impurities. It’s all over the map.
Purgatory is one entrance to Heaven, necessary for some, yes.
