Ties by yin_again - Teyla/OMC, Teyla/Ronon, Sheppard/McKay. Highly recced, both for the lovely story and the relevance to women's health. I'll use yin_again's summary: No one was particularly surprised when Teyla started dating. Several people were surprised that the person she was dating wasn’t Ronon.
It's very good, and very team, and very family.
