Sentinel Crossovers

[sarah he]

Hi there, I am having a rather particular hankering since I stumbled upon the series Sentinel 101https://archiveofourown.org/series/54155 where John is the Guide rather than Rodney. So I am wondering whether there's other stories like this. I'd be delighted if you know some but I will take any Sentinel crossovers tbh, I'd appreciate it if you mention who's the Sentinel and the guide. Just so I can prioritise what I want to read first... Thanks guys 🙂
