Mesopotamians to the Rescue!

Question: How does Subsumation of Me work with defensive knacks that allow the user to intercept attacks? Can you still have the option of diffusing a lightning bolt meant for another player? Or should they just have to take it on the chin like everyone else?

While most of the time diving in front of an attack meant for someone else is going to land a Scion in a world of zero-DV pain, in this case, yes, Me can help prevent that! A Scion can indeed take an attack and use Subsumation of Me to successfully avoid being hurt by it if it happens to be from the purview she exerts some control over. (Although, in your example, she'd probably be better off just turning on Lightning Rod and calling it a day.) Of course, Subsumation of Me requires her to win a roll, and she risks being fried by god-level electrical bolts if she fails, but those are the dangers of throwing yourself in front of your comrades.

Of course, a great number of the ways people can put a hurting on your friends with purviews can't be intercepted and blocked that way - for example, you can throw yourself in front of someone all you want, but Inferno is still going to toast them because it's toasting everything in the vicinity - so this is definitely not a foolproof method of saving your friends for free all the time, and it won't save you from good old normal damage to the face if an enemy happens to decide to combine lightning bolts with punches. But for the altruistic Scion of the Anunna, Subsumation of Me gives them an option to save the day and try to do it without getting their face fried off or pounded in, just as a normal Scion can try to do so with Skin-Shedding.
