So im a huge clarktavia shipper, and recently, I came up with several clarketavia aus mostly set during season 5 and on
1. Clarke and Octavia are secretly dating
Instead of Ilian following Octavia into that cave, it's Clarke, and the two of them end up hooking up
They end up dating in secret, but Clarke still goes with the others to rescue Raven and gets left behind, as in canon
Octavia still becomes Blodreina, and she ends up in an even worse place mentally and emotionally because now she's grieving not just Lincoln but Clarke too
When they are reunited, this drives a wedge into Clarke and Octavia's relationship, leading to them breaking up during the events of season 5, and just like in canon, Madi is made commander, and Clarke takes her and flees back to the valley, except Clarke was never arrested and never tries to kill Octavia instead a very protective Octavia who is still in love with clarke becomes even more obsessive then ever before wanting to win the war and reach clarke and madi before they can get hurt by McCreary and Octavia is angry with Bellamy for making Madi commander and driving her and Clarke off which is why he and Gaia end up in the arena
The valley is still destroyed, and they still all go into cryo sleep, ending up in sanctum, but Clarke and Octavia are exes that still love each other but haven't gotten back together
Bellamy still sends Octavia away, but neither Clarke nor Madi is happy about it
The entirety of the plot of season 5 still happens, but with Clarke and Octavia fighting to get back to each other, and Octavia being determined to save Clarke after she is possessed by Josephine, and the two of them end up getting back together after Octavia saves Clarke
(sidenote I had the thought of Octavia being jealous of Clarke and Niylah's past together, but since she and Niylah are friends, she doesn't say anything, and after her and Clarke break up, Octavia ends up feeling insecure, fearing that Clarke might get back together with Niylah until her and Clarke get back together and clarke reassures her that she and Niylah are done.)
2. Octavia hears Clark's radio calls
I was inspired by reading the fics Radio calls by Royal-Phoenix 7000 and the Wanheda en Skairepa series by JET_MacLeod

during the season five time jump octavia ends up accidentally receiving all of clarkes radio calls to bellamy and spacekru over her own radio in second dawn but for whatever reason it only goes one way with octavia being able to hear Clarke but not able to respond to her
-This leads to octavia falling in love with clarke through listening to her on the radio and either
A.clarke manages to open the bunker
- clarke fails to open the doors the first day in polis and so she leaves finds the valley and adopts madi as she does in canon but like maybe 2-3 years in after years of her and madi making repeated attempts at clearing out the rubble to get to the door they manage to reach second dawn and get somebodies attention for them to open the door
- so now clarke and madi are living in second dawn as a part of wonkru and clarke and Octavia are slowly falling in love and Co leading the bunker together
- also Clarke's relationship with Madi leads Octavia to take a more active role with Ethan with her essentialy adopting him
- eventually clarke and Octavia officialy get together and are a happy family unit raising madi and Ethan together and leading their people with clarke and Octavia as the queens and madi and Ethan as their heirs the princess of death and the red prince/prince of blood(the titles are maybe a work in progress but you get the idea)
- with the bunker open the dark year never happens and by the time year 6 roles around and eligus shows up all of wonkru are already living in the valley meaning diyoza and everybody are forced to negotiate and share the land
B.Clarke doesn't manage to open the bunker
-similar to the above but clarke and madi never manage to open the doors to the bunker so the events of season five mostly happen but with octavia secretly pinning after clarke while clarke is oblivious
-with the bunker not being open the dark year still happens leaving octavia traumatized but she's alot more willing to listen to clarke's advice amd so avoids some of the mistakes she made in season 5
- Octavia adopts Ethan and he is the prince of Wonkru
-All of wonkru knows about octavia's feelings and views clarke as another queen both because of Octavia and because they still remember Clarke as wanheda and they view Madi as their princess
- Octavia is still banished during season six and has her adventure with diyoza but her motivation to get home is about getting back to clarke and their kids not Bellamy and diyoza is alot more understanding of that
- Ethan lives and he and Madi form a sibling like relationship with clarke looking after him while Octavia is gone ad the two of them simultaneously lose their minds after clarke is supposedly killed by the primes but they also keep each other more stable then they would be alone and are determined to get their moms back and get them together
3. Clarke manages to get the doors to the bunker open and rules with octavia
- similar to the above two but without the radio calls
- clarke gets the bunker open that first day
- clarke and Octavia end up co leading the bunker similar to how clarke and Bellamy where running the 100 back in the day and they end up being a slowburn
- clarke being the only night blood ends up traveling around which is how she finds the valley and Madi though a little later than in cannon like say year 2
- clarke uses her own bone marrow to create the serum and over the corse of the five years turns everybody into nightbloods
- similar to the above with wonkru already inhabiting the valley wonkru is forced to share the space and either everybody lives hea or fighting still breaks out among the groups and the valley is destroyed leading to them going to crysleep and arriving in sanctum with the events of season 6-7 happening with clarke and Octavia as an established couple and family unit having adopted both Madi and ethan or maybe somebody on earth discovers and activates the anomaly stone or vice versa somebody on either sanctum or Bardo activates the stones ending up on earth and everybody gets pulled into the drama of season 6-7 that way
4. Clarke and Octavia are not together but have been crushing on each other for a while by the time they get to sanctum the events of season five have caused a rift between them but they still like each other and are now pining
- octavia and clarke have had feeling for each other for a while but never acted on them
- season 5 drives a wedge between them but during season six clarke grows closer with Jax and Miller again with spacekru iceing her out
- Octavia rescues her from the primes and they confess their feelings getting together
5. Fake dating/marriage of convenience turned real relationship au
A. Clarke takes a chance and tells octavia the truth about Madi
- During their conversation in the tent when Octavia asks about Madi instead of lying clarke tells the truth and the two of them form an alliance pretending to be together to both consolidate octavias power and take back the valley and to protect Madi
B.clarke makes it into the bunker but still finds Madi and her and Octavia end up adopting her together
-(could honestly go with any of the above fic ideas but...)
- Clarke is in the bunker she ends up finding Madi but it's a little too late to go with the same lie in canon about clarke donating bone marrow so Clarke and Octavia either pretend to be together and marry or they already are together and adopt her to keep Madi safe as their heir and the princess of wonkru
