[Full Metal Alchemist] So what *did* the Elric brothers and Izumi summon if it wasn't their loved ones?

Just finished watching the show for the first time yesterday. I was a little bit curious by that plot thread -- it seemed like the fact that the skeleton for Trisha and Izumi's baby weren't consistent for them would've been a bigger deal, but it doesn't seem to go anywhere. Or did they answer this more subtlety and I wasn't paying attention?

On a similar note: is Rebounding a bigger deal in the manga? They introduced it as a concept pretty early in the show, so I figured it was going to be an important rule of alchemy that would be used in the show but they never really address it again either.

They didn’t ‘summon’ anything, they just made a twisted mass of flesh out of the ingredients provided.

Imagine it like a LEGO set put together by a child not reading the instructions. You might get the general shape out of it but it’s not going to be right. Same deal.

I’m assuming you mean Brotherhood, the original anime takes a very different route.
