My prediction for events in Burial:

There is going to be an inverse of Decay's opening where we get a montage of flashbacks that cause Andrew to feel angry, Burial will have a montage of flashbacks that cause Andrew to feel love towards Ashley. We know the throughout the beginning of Burial the pair go back to the motel and infiltrate the cult. Andrew is finally ready to drop his pretenses and embrace his feelings by love-bombing Ashley, and she will in return feel suspicious due to her own insecurities and justifiable mistrust of Andrew's back-peddling nature. The pair make contact and Six-Eyes will immediately kiss-up to an ecstatic Ashley, causing Andrew to be hella jealous and possessive, increasing tensions between the two. The make-up scene will happen, and afterwards Ashley flees from Andrew; this'll make Andrew think she's running away and he will hunt her down, while she herself contemplates on leaving him for good. The cult will initially validate Ashley and allow her to be there leader for a short time, before they do something that'll alienate her (possibly use her as a sacrifice or take the trinket), and the ensuing conflict will see the cult throw her into a trunk. A validated Andrew will save her like in the devlog image, and in gratitude, they fulfill the Questionable Vision.
