Hi, folks--me again.
Quick reminder: most rites require at least three participants. The exceptions to this rule are most Mystic Rites (which are designed to be performed alone) and any rite which explicitly states that it can be performed by fewer than three participants, either in the rulebook or in the current errata.
Other than that, rites take three participants, minimum. Try to do it with fewer than that, and it's just not going to work.
