15. Angel And Spike Have The Same Name
One of the great rivalries on the show is that of Angel and Spike. When one is good and the other is bad, they flat out hate each other, and when they're both bad, they hate each other and when they're both good they still... well, you get the idea. Yet despite their ill feelings, the two have a lot in common. Some of the similarities are fairly obvious - they both love Buffy, they both acquire a soul, they both have a fondness for black coats - but one in particular acts as a fun easter egg that's easy to miss. Spike is alternatively known as William the Bloody while Angel's rarely used real name is Liam. In Angel's native Ireland, Liam is a form of William, and thus the rivals have the same name. Is this a deliberate nod to the duo's duality or just a happy coincidence and a sign that Buffy fans look too much into things? You decide.
