They were in another timeline. It happened occasionally. Who even knew how Wade got involved. He was just trying to show Darcy how many tacos he could fit in his mouth (six), and then blammo: Big flash of light, whirling space vortex, the indescribable sensation of the universe contracting with you inside it to the size of a single electron, and then everybody was spat out in a heap on the sidewalk of a place that looked like -- but probably wasn’t -- New York, and all of Wade’s tacos de sesos were lost to the interdimensional void. “Nooo,” Wade whispered, heartbroken. “Tacos.”

Something strange happened to Wade. Well, something strange always happens to Wade. But this type of strange involves an alien ray, Wanda (aka Lady Deadpool), and some slight errors with his regeneration in another universe. Luckily, the Merc with the Mouth has an Ultimate Amazing boyfriend and a newly adopted sister/doppelganger to help him through. Or Deadpool is atomized, and comes back home with lady parts.

"That right there, that right there, is why I know it's gonna be a lie." *** Peter befriends Loki, and then some.

Peter’s first post-mission Avengers hang out goes about as well as one would expect.
