(Side note I'm only doing the main if routes because I don't have enough information about the others and I'm going of memory also I am adding seens that are my take on how I'd see Subaru and Rem as parents I get that we do see them as parents for a adolescent Rigal but there is nothing about how they raised him when he was younger I do hope you injoy)
Tarn: okay we are going to see a different time-line
Reinhard: i thought we were going to see a different world
Tarn: yes but I figured might as well see the different time-lines as well so enjoy especially you Rem [points at Rem]
Rem: why?
Tarn: because this revolves around you and Subaru
Ram: WHAT!!!??? [Tackles Subaru unconscious body and starts strangling him as he has no reaction]
Rem: sister stop[goes up to Ram and tries to pull her of Subaru]
Garfield:captain [helps Rem pull Ram off subaru]
Tarn: [grabs all three of them and sets them in their chairs]
Ram: how did that idiot manage to get a relationship with my sister
Tarn just watch and see
[We open to see the inside of a dragon carage we here someone whispering]
???: I'm sorry, please forgive me
[The camera shows who is whispering is none other than Natsuki Subaru who lying in the lap of Rem who is rubbing his head]
Otto: what is Subaru sorry for?
Tarn: I'm going to keep that to my self for your own sanity
Otto: [sigh] okay
[We then timeskip by 1 year and we see an apartment and we see Rem with longer hair open the door and enters the house]
Rem: Subaru Rem is home
Subaru: hey Rem how was your day
Rem: it was quite nice the children were so excited to learn today
