Apparently, a congratulations is all you need to do to win the loyalty of Deadpool. It all started when Chris Evans(Captain America) sent a Tweet to Ryan Reynolds and ended with some hurt feelings from Ironman/Robert Downey Jr.
But Deadpool can be fickle...
In the end, he chose the only side worth choosing. #TeamHelloKitty will surely come out on top in Captain America: Civil War.
