The Flash Season 3: 10 Things You Might've Missed In 'Flashpoint'
10. Big Belly Burger
If you are a regular Arrowverse viewer, you will recognise the Big Belly Burger brand name, as the fictional fast food chain has outlets in both Arrow’s Star City and The Flash’s Central City. As such, both bands of heroes – though, in particular, the STAR Labs team – frequently get take-outs from the establishment.
In Flashpoint, Barry feeds the imprisoned Reverse-Flash with a Big Belly Burger meal. This may be a callback to season one’s finale Fast Enough, in which Eobard Thawne – in his Harrison Wells guise – admits that one of the few positives of being stuck in the 21st century is the company's burgers. Apparently, by his time, cows have become extinct. Presumably Barry forgot Eobard’s fondness for the grub when bringing him some here. Or maybe he just wanted to make amends for locking him up for three months.
Big Belly Burger also seems to be the one constant of the Multiverse, as this is the second time we have seen the eatery in a different timeline/universe (it likewise existed on Earth-2).
