Interstices, in Roman Catholicism, are periods of time required by Church law between grades of Holy Orders. Under particular circumstances, a bishop may shorten the period, though it typical lasts for three months, sometimes longer.
Interstitial time can obscure recognition of toxicity. For both clergy and soldiers, interstitial time (between Holy Orders, between deployments) are built into practice as protective mechanisms in order to ensure the subject is "ready" for the next stage of their service. Yet, during interstitial periods, the body often becomes dislocated from the site of toxicity. Once toxicity is recognized, it becomes difficult to apprehend without colocation of the body.
