magneto quicksilver and scarletwitch

i know you guys might move this but im putting this on here cause no one even answers it saying they dont know atleast on the comic books forums . so can you leave it on here for awhile if its not to much to ask.

which book did magneto find out that hes quickslivers and scarletwitches
father ?

Sorry, I won't move it, but it's already in the Comic Books forum, so I'll have to close this one.

Just be patient, threads don't always get answered right away.

Although, you could try to Wiki or Google it if you're in a hurry.
