@Beavo Yeah I found this out a short while ago, I probably should have updated my comment. I saw it in a video the devs made playing old versions of the game.
Ted is better for expeditions late game when you need more supplies and it's better because he's more likely to bring something good back. The reason i brought Timmy is because he is the best scavenger out of the 4. Dolores maintains sanity way better than Ted so it takes a good amount of luck for Ted to remain sane in runs. Overall id probably say Dolores + Ted is better just because of the sanity factor.
Edit: A short while ago I found out no one person is better than another at scavenging, I was pretty surprised to learn this. Its in a video by the devs on youtube playing old versions of the game. My opinion about Ted + Dolores still stands however. Sorry to any confusion this may have caused.
