I was struck in the Spinner’s End chapter by the parallels between the “good” and “bad” sides of the wizarding world. Our titular protagonist was saved by a mother risking everything to save him. Now the mother of one of his principal adversaries is . . . risking everything to try to save her son.

Similarly, the “good” side spent the entire previous book beleaguered by infighting and politics: who has the right of it, who can be trusted, etc. And now here is the “bad” side . . . beleaguered by infighting and politics: who has the right of it, who can be trusted, etc. And of course Snape in the middle of it all! It makes me really want a scene with Voldemort cartoonishly saying to Harry, “Are we so different, you and I?” 😛
***SPOILERS BELOW***
In response to a theory from another member of my Harry Potter book club that Bellatrix is so angry at Snape here because she is in love Voldemort, I must . . . disagree. I find the Cursed Child’s plot point of her having a child with Voldy to be a preposterous mischaracterization. I think Voldy would have been effectively asexual, finding love/sex with mere mortals far beneath him. Possibly in his younger, Tom Riddle days he might have used sex as a way to beguile someone into giving him something he wanted (although even in the case of Hepzibah Smith his malicious “charm” is never indicated to go nearly that far for Hufflepuff’s cup). However, by the time he became horcruxed Lord Voldemort, I don’t think he would have even been capable of sex.
I also never read Bellatrix as sexually attracted to Voldy. Her behavior seems very in keeping with any sycophantic underling who is jockeying for the position of “favorite” of someone who is very powerful. I see her antipathy toward Snape as jealousy – he didn’t even have to go to Azkaban and yet he is still so “inner circle” to Voldemort that he gets access to privileged information . . . IT’S NOT FAIR!!!!
But there is certainly nothing wrong with us each having our different head canons! 🙂
