we all know how much killing eve's writers love parallels and we've been seeing a lot of those in thjs current season and this got me thinking about one possible ending for the series so bare with me for few minutes
so, the parallels between the season finale of season one and of season two are obvious: eve stabbed villanelle and villanelle shot eve, they both hurt each other and they both think the other is dead
now, about season three: eve and villanelle meet once again, they face each other once again and then go separate ways (this is my personal interpretation since the bridge scene is yet to be acknowledged this season) but clearly something happened between the two of them that got them to go separeted ways once again
now, we know the finale scene is with both eve and villanelle together (i believe sandra or jodie confirmed that) and since i don't believe they will die but most likely they'll fake their own death (maybe with Pam's help, the imbalmer?) and we will see them together in the end, maybe meeting once again after a couple of months/a year once the waters but have settled but this time they won't go away from each other but they'll stay together
