Ok, I get what you’re saying about the OUAT ‘flashsideways’ as opposed to the LOST ‘falsh’…the events in both OUAT ‘worlds’ were actually happening at the same time, where as LOST was not. I do, however, consider the events happening in 1977 and the events happening in the ‘present’ as flashsideways. Although the year 1977 was obviously the past, the events with jughead, Jack, Sawyer, Kate….ect….were happening at the same time as the events in the ‘present’ with Des, etc…
