As you all now know, Henry will getting himself mortally wounded trying to defend Hope from Delight alongside Saber, but not before getting out the SOS you're all waiting for! After that's done he'll hang on just long enough to shield Hope until help arrives.

Sorry, Nick V., for leaving you in charge of the Guard.

He'll get revived, so people who want to kick his arse for dying please form a queue. I haven't finalised what the consequences of his revival will be yet, so that'll be a surprise. Nonetheless, he'll jump straight back into the fight against the Null.
