Where do you get the missions for the BoS where you have to escort a young squire? I've got the ones where you go with an advlt and get some tech, but I can't seem to find where to get the other ones.

Thanks.

You get that quest from Kells, after completing all of his other quests like Lost Patrol, depending on how far you are in the story Blind Betrayal, Tactical Thinking, A Loose End, and Duty or Dishonor.

Which consists mostly of the Squire, hiding behind you and telling you how awesome you are. According to some this constitutes 'blooding them in combat'. Personally, I got a lot bloodier when my uncle took me deer hunting when I was 8.

Hmm ... I never actually gone back to him to ask for missions. I just get them from Teagan and Quinlan, plus turning in documents and blood. Are there others for the BoS that give out quests? Wondering what I've been missing now.

As far as the end game is concerned, you can get radiant BOS quests from Scribe Haylen and Knight Rhys at the Cambridge Police Station. The 'Feeding the Troops' quests from Proctor Teagan, the research patrol quests from Proctor Quinlan, and the squire training quests from Captain Kells. I think that's it. There's also the technical documents, viable blood samples, and reactor coolant that you can always bring them but those aren't really quests.

Reactor Coolant? Hadn't heard of that one either. Who gives that one out?

Proctor Ingram gives it out. That one doesn't become available until after completing the main quest though.

True, on the other hand this is less stressful than the Suicidal Scribes who tend to try to get killed (I had one die at the airport waiting to be collected) by refusing to use stealth and charging groups of enemies at every opportunity.
