Since there is still a lot of potential for the manga and show I think there are a lot of fun plots in the future. However, this is about what you want to see. Here is what I would love to see before SpyxFamily concludes:
- Yor having a pregnancy scare. She would blackout after getting drunk and almost kissing Loid previously and she picks up gossip from her coworkers how someone else got pregnant and she misinterprets her own symptoms. When she later realizes she's not pregnant she feels embarrassed and relieved but still thinks it'd be nice to happen one day.
- Yuri falling in love with someone so he would potentially act less possessive of Yor. I could also see it as a mission for Loid so he would be less occupied with Yor and less suspicious of Loid in the long run.
- Loid running into Karen. She would recognize him as Robert but she dismisses it after he reveals he's married with a child for a while so he must look just very similar. However, some suspicion lingers and it would be an icebreaker for a whole storyline and further mission related to the past.
