They "MERGE," with the superior timeline, no matter how many there may be, having priority over the inferior timeline(s). It is the same with Trusts. If one wishes to extinguish a Trust. Say, for example, an IMPLIED TRUST. That can be accomplished by the Expression of a New and Better Trust, which of course would automatically be deemed to be the superior Trust. For that which is IMPLIED, operates under presumption; whereas, an Expression is indeed a proclamation of one's Will which, shall we say, can be trusted. Essentially, the two or more Trusts effectively become one new and better Trust. [Maxim of Law, "That which is EXPRESSED will always Extinguish that which is IMPLIED." (Emphasis added]
Definitely an ah-ha moment by connecting with the mechanics of a trust, and maxim of law; well done!
Lemme ask a follow-up question: Would one expect to encounter people who are reminders of others whom one has come into contact during previous timelines? Example: one crosses paths with someone who reminds them of a loved one, long-lost friend, etc.
