For reference, that info from the first panel is straight from Hamada's bio from the movie, as can be seen from the TL that's posted on her Danbooru wiki page.
I had a Theory That Kiyo Hamada is Hiro & Tadashi's (Big Hero 6) Real Mother Because GUP is Set in 2012 & Big Hero 6 is set in 2032 so It's Possible Kiyo Got married in 2014 Had Tadashi in 2015 Then Hiro in 2019, 10/17/2029 3 Years Before Big Hero 6 is set She Dies in a M6.9 Earthquake in Sanfransokyo Because of the City's Namesake of Combining San Fransisco & Tokyo And thus Hiro & Tadashi's Possible Real Mother is Kiyo Hamada.
What Do You Think?
