Even now, months after she wrapped production on Season 1 of “Monarch: Legacy of Monsters,” breakout star Mari Yamamoto gets admittedly emotional while talking about the show’s finale.

The actress plays Keiko Mura, a Japanese scientist who, in the 1950s, helped start the organization Monarch alongside Bill Randa (Anders Holm) and Lee Shaw (Wyatt Russell) to understand and study Godzilla and other Massive Unidentified Terrestrial Organisms (MUTOs). But after a mission gone wrong, Keiko is presumed dead and is only later discovered to have survived, barely aged for decades, within a part of Hollow Earth she’s coined Axis Mundi. It’s there, in the show’s finale, where Keiko reunites with an elder Lee and realizes that her 57 days spent in Axis Mundi have translated to literal decades on Earth.
