A seemingly innocuous detail that Deadpool's origin than previously suspected. The visual cues from one issue hint that Wade Wilson may not originally be from Earth-616, especially when considering that his past is riddled with contradictory details and falsities.
Gwen isn't from Marvel's Earth-616 completely calls Deadpool's backstory into question.
Gwenpool's tell that alerts Doctor Strange to her other-worldliness is her speech balloons. He can see her speech balloons and notices that they're pink, which is in sharp contrast to the white bubbles of everyone around her. In fact, Gwen even sees her speech balloons briefly when Doctor Strange takes one for a spell casting. He describes her visual speech as a "cosmic accent" that solidifies she's from another world. Both she and Deadpool share uniquely colored speech balloons, with his being yellow. Going off of Doctor Strange's assertion that the balloon coloring signifies someone is from another reality, this hints that Wade Wilson may not originally be from Earth-616. This origin theory makes sense when considering Deadpool's contentious and vague past, and his incredible second sight that can cut through the DNA of any reality to determine what's real and what is not.
It's worth noting that variations on normal speech balloons are a consistent way for Marvel to indicate that characters are from different realities. A popular example is Ultimate Reed Richards, or Maker, whose speech balloons are in lower case rather than all caps because he's from the Ultimate Universe. This tactic is an excellent visual distinction that helps fans to know when there is a potential dimension-hopping character in a comic without being directly told by writers.
Although The Unbelievable Gwenpool is considered a fun short-lived adventure, this surprising new detail from Doctor Strange that adds another layer to Deadpool's origin theory. Deadpool is a uniquely antagonistic character in Marvel Comics, so to see Gwen emulate his style and be referred to as a cosmic newcomer by Doctor Strange strongly suggests Wade Wilson's origin is far from simple. The visual parallels between Deadpool way of speaking and Gwenpool's cosmic accent, combined with Marvel's penchant for using speech balloons to show characters who aren't native, hints that Deadpool's origin is in a different dimension.
