Emergency home-time relocation is a feature of the GIGAHERTZ . It immediately returns the characters to the present, without needing coordinates or calibration - it simply synchronises the comic number on the page with the number in the URL. For this reason, it is most useful when the characters are in a hurry and do not have time to set the destination time. The page image shows the only time emergency home-time relocation has been used so far - Jane suffered a bout of hat deprivation illness while in the past, and Trope-tan needed to bring her to Fred for treatment.
