O.B. supplies the episode's explanation of the crisis: the Temporal Loom was designed for a single timeline and cannot handle infinite branches, and Loki must find his friends across the branches before they are spaghettified (Stretched into strands and destroyed by extreme gravitational forces).3 The episode ends with Loki's time-slipping landing him back at the TVA just before the Loom meltdown, teeing up the season finale.3
