Wait I didn't realise the baby was so big

The angel was the one who is small, remember they made him small and put him in a jar

But didn't like go thru a door and didn't go under the smallifying process??

No they didn't include the spell on how they (the demons) made those angels small. They just show them (angels) inside the jar already, just like in previous chap.

Ohhhh i seee
