Was Justine a slayer in the "Buffy the Vampire Slayer's" spin off दिखाना "Angel"? If not, then how was she that strong, and if she was, why was she so much older than any of the other slayers?

A) Perhaps this is a better सवाल for the एंजल spot as (though I think it's a real shame) not every Buffy प्रशंसक is a प्रशंसक of एंजल the Series, and have no idea who Justine is या what you're talking about.

B) I recently rewatched एंजल last साल and I don't recall Justine being supernaturally strong. She trained a lot with Holtz, but she was fueled द्वारा revenge, not Slayer power.

C) Age is no indication of whether या not you're a slayer. The only reason there aren't a lot of older slayers is because slayers are normally called when they are teens, and generally have abreviated lifespans as a result. If anything, an older slayer (and द्वारा "old" I really don't mean so old - but like 30s या 40s) should probably command some respect. After all, it would दिखाना that she's survived that long. I like to think of Buffy in her 40s, being such a strong slayer, even at middle age.

No, I don't believe that she was a slayer. She was probably just strong because she trained after her sister's death.
As for the age thing, even though it seems like most of the slayers were called in their mid to late teens, I dont believe there was any hard and fast rule for how young या old they had to be.

I like to think Justine was a 'half-slayer'. After her sister died at the hands of vampires, she was 'called', due to the Slayer dying at the end of series 5. However, because Buffy had already died once before (and as a result meant that Kendra was called), her सेकंड death only gave Justine some, but not all of the usual Slayer power & attributes.

Works for me, anyway!
