There are many errors with the city map in this episode. For example, when Izzy's laptop map shows him to be in one place, Machinedramon's map shows him elsewhere. Also, in the English dub, the Hagarumon track Izzy's laptop to "sector B-17", shown to be on the left side of the map, though when "sectors A and B" are destroyed, they're both shown to be on the right-hand side.
When Kari coughs while talking to Tai, her face disappears for a brief moment.
