Grace wakes in the hospital after a near-fatal asthma attack at the well site she's studying. Faced with another major failure, unexpected visitors, and absurdly high medical bills, she tries to carry on as if nothing has changed.

Grace has a sweet moment with Ned just before receiving devastating, life-altering news from the dean of her department.

As Grace wrestles with her estranged mother Francesca's illness, Ned accompanies her on a visit and volunteers them for duty in the neighborhood vegetable garden, where they learn just how beloved Francesca is in her community.

Grace and Barbara argue about the narrow scope of their methane research, while Grace tries to push away a growing sense of unease about Barbara's loyalty.

Grace is creating a definitive map of methane emissions from United Energy’s wells. Dragonfly Farm is the largest tract of land in the area, not under lease for methane extraction. She needs to sample their air as a baseline, to contrast and highlight methane hot spots from the well sites. She makes her pitch to the owners of the farm, but they know about her connection to the drilling company. They question her integrity and make a shocking demonstration that challenges Grace's closely held belief in the value of her work.

Grace contacts the owners of the farm adjacent to the methane well site to ask permission to place her air monitors on their property. They invite her to one of their Radical Self-Sufficiency workshops and promise to discuss her proposal afterwards. Now she’s burning an entire Saturday for something she learned the hard way—by living it. They said to wear old clothes and be prepared for mud.

Grace spends money like a drunken sailor to equip her lab with all new equipment, resists a strange mentorship, and spars with Ned, a reporter for the Sun, over their coverage of climate.

Grace's mother cooks her a fancy Italian birthday dinner, then delivers news that rearranges Grace's life.

A cocky executive from the fossil fuel company first questions Grace's integrity and threatens to cancel her access to their well sites, then makes a surprising offer that would supercharge her research and prove just how valuable it (and she) is.

Warbird’s new well casing is throwing off crazy high methane readings. So are Dazzler and Beast. Three out of her eight sites. It’s alarming. She suspects the casings are cracked, but given the gaps in her instruments’ readings, she needs more data. And more reliable equipment, but that’s not happening. She’ll make the best of it. She always does.
