How to show children in rem back of card/answer?

Just getting started. Wanted to make a rem where when you see the back of a card, it will show some additional useful images/points. I thought one way would be to show the children below (see example). However when I do it this way, it does not show the child in the answer. Any way to get around this or design it so that when you see the answer you also see associated images/children? Sometimes useful for context.

example:

Add the ##Extra Card Detail tag to the child.
