Man tappei and whitefox are literally genius man

So I was watching the season 2 ep4 of anime again and I just realized if you see the figurines that subaru

Has on his shelves you will see siesta from detective is already dead light novel and anime and also if you look at the first poster in his room you will see the volume 1 cover of it (which was blurred but idk why)

So well basically I was watching the season 2 again and it left me wondering will season 3 because you know white fox rarely does more then two seasons with re zero no exceptions are there (even though the popularity has increased after season 2) plus the next arc is a war arc and I have heard white fox are very poor in doing wars animation so I dont think season 3 is possible (although I want it badly and see shaula animated so i can die peacefully imao)

It seems that Elsa's death book is hidden by design ,Subalu hasn't read it.

Could he be helpful

In my opinion the key to Rezero is Echidna .She connects to everone. She could control soul.According to this book soul is named after ode which is the name of the goddess Ode Raguna,besides she has the book of wisdom called the memory of the world.Maybe she is one of the goddesses' successors，rulering memory and souls.

Where can I watch it?

Some of my friends say to just read the novel while my other friends say it's more fun to read the manga.

Does the manga also cover the whole entirety of season 1 and some of season 2?

I've seen memes of rumors saying Emilia pads her chest. this is kinda niche but, i need to know whether its just a joke or fr. (its def a joke but, these kind of questions make me question my life)

I have been also been seeing some parts in the manga that I don't think were ever shown in the animae.

SPOILERS ALERT

I have seen rem with long blue hair holding a baby in her hands and then a kid standing next to Subaru. Apparently, this was in season 2? I have never seen rem with long blue hair so.............................wtf?

Does the manga show more info from the novel than the animae????
