Make sure you tell M, T, and any other potential partners early
that they are disposable so that they can make an informed decision about becoming involved with you before their emotions are engaged. It's not fair to lure someone in with the promise of a relationship only to rip it out from under them on a whim, particularly if they've had time to become attached.
