What if when the avengers raided the Hydra base the twins were at a start of escaping. Lena helped the twins escape- she was as well a test subject there.
Lena was the Maximoff's neighbor she was the only survivor of the blast, she crawled over to the twins and stayed with them for those two days.
The avengers do everything to try to catch the three but they are too slick, Lena has powers similar to Wanda's but with no mind control or mind reading, they run for help- help of the wrong people.
