So Gambits thing wasnt really an inside joke, it was well known his movie was cancelled, which is why the running gag throughout the film after Gambit appears is vague answers and paradoxes like he was born in the void (because his movie died before release) but remembers being shot outta his daddies parts (the idea was there). His accent is actually pretty on point especially since his dad grew up around the bayous of Mississippi using the real accent and based it on that, if not only just a touched embellished for the comedy.
Wade is shown wearing the time slider when talking to Happy. It lets him cross dimensions as well.
With the watch
