What are the chances of this happening? Is this fairly common?

So she owned an adult lavander albino. When the albino was in my house we tried to feed it rats but unfortunately it didn't eat it but it did eat a medium mouse. Fast forward to a week later it wouldn't eat anything. Not even a medium mouse or rats. On the same week we went to a show and bought a baby ball python. When she brought it home she house it together by putting the baby ball python inside a tupperware container. The next day she said that the lavander albino was on top of the tupper ware as if keeping it warm. I thought otherwise but figured whatever.

The next day she decided to change her set up and put them side byside by putting them both in a tupperware. basically two tupperware holding one snake each right beside each other. She was doing this as a temporary solution until she can fix the whole setup. Now she came home and found them both missing.

She came home and saw that her home made carboardbox enclosure housing both tupperware was slightly open. When she looked inside she found that both snakes arent in the tupper ware. Mind you that she taped the adults tupper ware cage and put something heavy on top. the tupperware holding the baby was open but the lid was still on top. She searched everywhere for both of them. She found the lavander albino underneath her bed. But she can't locate the baby ball.

She thinks that the adult ball might've eaten the baby ball. with makes me sick to my stomach since i'm a failry new owner myself. She checked everywhere in her room and she doesn't think that the babyball is small enough to crawl outside of her room which led her to this conclusion. I said it might be possible since i'm really hoping that babyball is still alive and if it is she has to find it fast.

Her room is small and she checked everywhere. I told her to check the rest of her house since you never know.
My question once again is it possible for the adult to eat the baby ball <---i actually checked this on google they said yes if the size is different enough.
mind you this ball python was offered both rats and m size mouse the day before and refused to eat.

Both are males. Albino is 3 years old the babyball is 3 months and we just got that baby ball this sunday. Her room is completely dark and this whole thing would've happened in a span of 12 hours since she left her house for work until she came back.

I told her to check everywhere.

Any suggestions on how we can find the baby ball if its still alive? How long can it live in a house environment? If the albino did eat it any way we can check.
Sorry if its hard to understand i'm in a rush to head out. For those that can comprehend it any help would be appreciated. and if nothing else a prayer that the babyball is alive hiding somewhere.
