They've been going backwards for a while now. Ultimately it turned out the super secret room they wanted to infiltrate was where the bad guy is growing his weed and has nothing to do with the sister, so they have absolutely nothing and it turned into a humiliation ritual for MC. Also it turned out bad guy had her sister's phone the entire time and that's why he is so interested in her.
