It’s okay, IW’s ending was just one of the timelines Strange saw. In the real timeline, Wanda said yes to staying with Vision and they decided to travel the world! The Northern Cascades were their first stop.

They can spend awhile there, since Vision only carries provisions for Wanda. Wanda likes the mountains–they remind her of Sokovia. Vision likes that it’s mostly wilderness, so he doesn’t have to worry as much about staying in disguise. Wanda has perfected a low-level telekinetic field that acts as a mosquito repellent. Vision, on the other hand, gets excited when a bug lands on him. He is particularly fond of northern bluets.
