you've been traveling around Skyrim with Serana by your side after everything though before you met her you did kill Alduin which took forever and got super hard but you managed to do it and got all the shouts given how many you've come across but anyways after being together for so long you both do slowly end up in a relationship not a quick forced one just slow and easy relationship she's comfortable with and before you know it four years went by and now she's pregnant with your child though you went down the becoming a werewolf route the baby is an interesting combination so while you go on adventures she stays in Whiterun where it's safe though you always come back to her afterwards but now that she's eight months along your staying nearby rather than going out
