Cho/Jane/Rigsby
Patrick Jane was a functioning Sentinel with his wife/Guide until she and their daughter were killed. Many feared Jane would die as well, but he lived through his zone out and became a criminal consultant to the CBI.
Kimball Cho was found to be a Sentinel in the Army and had a set of rotating Guides before finally finding a permanent Guide in Wayne Rigsby. Rigsby was reluctant to be a true Guide to Cho, but they clicked immediately and soon became the best Sentinel/Guide team in the CBI.
When Jane arrived, Rigsby was ordered to be his Guide as well, as no one else wanted to or couldn’t connect with him. Jane consented, but only if Cho agreed. Jane made it clear to both Cho and Rigsby he had no need for a physical connection and only needed a Guide if he went into a severe zone out.
It’s been a bit awkward for the threesome, but they have become closer as friends and Cho and Rigsby someday hope Jane would join them in having a complete Sentinel/Guide bond.
