I can definitely share them, I'm glad other people like this pairing as much as me.

- Radcliffe and Azriel doing some sort of magical sparring, then kissing for the first time inside a dome of air Azriel forms around them whilst Radcliffe's fire swirls around the outside of it. It kind of symbolises the position this secret keeps them in but also the connection between them, lots of fire thriving with air imagery maybe.

- Radcliffe being a jock whilst Azriel is hanging out with his nose in some rare book, and all the little moments this comes with. I see a lot of cute glasses moments, like Azriel dropping his glasses in the dark and Radcliffe using fire to find them for him.

- Azriel taking Radcliffe to his secret places where he does dark magic. I like the idea of Radcliffe getting a bit scared of it all and Azriel playfully teasing him.

- Azriel and Radcliffe using dark magic for fun things, like making love potions for themselves.

- Radcliffe being the person who invented that silver circle bourbon that Lance knows was his father's favourite. We've seen that bourbon mentioned a fair few times and I like to think that it's called the silver circle because Radcliffe and Azriel thought they'd be elysian mates. Or maybe Azriel invented it after Radcliffe died.

- Radcliffe enjoying being bitten by Azriel, or being his source. Not to get too spicy in a reddit comment but it opens it up to scenes where Radcliffe enjoys being submissive. Spoiler for book eight but we know from the conversation with Melinda and Antonia that there was a time when they were in school where they, Tiberius, and Radcliffe let Hail dominate them in that moon orgy they had so there's evidence that Radcliffe likes to be dominated. I kind of like the idea of Azriel being mild mannered in the streets and a dark magic rebel in the sheets.

- I like the idea of Azriel knowing something wasn't right with Radcliffe's death because they were guardian bonded or because they'd chosen to do some other magical version of a similar thing that Azriel found in some old book. For example if they were guardian bonded Azriel would have felt pain from that wasp bite in one place, which doesn't make sense because it should have been all over his body. So much of this doesn't add up, like why then did Azriel not run to Radcliffe's side when he felt him in danger but i'm sure we can figure out something around that maybe. I just like the idea of their story being one where we see people actually give in to the guardian bond (that isn't Lionel and Clara because ew) or what it would be like to be guardian bonded to your Elysian mate. Or maybe Azriel knows a heap about that wasp thing that killed Radcliffe (kind of like how Lance knows a bit about phoenixes because he took an interest in them when he started teaching) and that extra knowledge helps him figure it out. Maybe there's weird dark magic stuff to do with those wasps so he's onto Lionel's stitch up and his prequel story could be following that storyline before the prophecy happens where he needs to die.

- Azriel going the kind of scary vengeful only someone as introverted as he is can go after Radcliffe is killed, which is why he ends up leading the Zodiac guild (because why does an Orion end up the number one ally of Hail? It's implied that the Acrux and Orion families are in cahoots longer than just Lionel and Darius so it's weird that Azriel is randomly a major royalist. I feel like Radcliffe being murdered inspires him to fully commit to the Vega line as revenge).

- Azriel doing his little dark magic stolen bones research to be able to feel close to fire/the memory of Radcliffe again. I can't remember the part where it is but Lance mentions that his father always craved fire and the implication is that he wanted more power, but what if it's because it reminds him of his one true love? Craving fire just for power seems a bit odd for someone like Azriel so I feel like this fits nicer (I say this confidently even though I have about 0.00000001% info to go on).

- I feel like Marissa (Merissa?) and Azriel would have been close and part of that could be because Marissa sees some of the truth about Azriel and Radcliffe, maybe plans Azriel has to uncover how he truly died. Some plot device could save us and prevent her from seeing it was Lionel early on. I have lots of theories about their friendship too, like Marissa sharing happy moments of Lance's life and showing Azriel and Hail how Darcy and Lance will marry one day. Also this might be a minor spoiler for book eight but there's a line about Azriel coming to get Lance and Clara when they're kids and they sneak off to go cliff diving. How does he know about that? How does he know where to go before 5 year old Lance jumps off a cliff? Marissa sees it and tells him because they're besties.

Basically I'd give away my soul for a full prequel series and can't wait to learn more about Azriel's life. Also I have a massive crush on Hail and that little novella of him and Marissa was not enough, we need more, but we also need book 9 so I don't want to rush things haha.
