Jill helped in the Nether, focusing on non-traditional aid but also venturing out looking for ingredients.
At Istredd's recommendation, Jill helped host the welcoming party for new Thorne arrivals -- including reaching out to local businesses for catering.
Jill also put in for representing Thorne on the Summoned Council, making sure to stress that she cares about Thorne's citizenry as well as the Summoned in her statement.
She and Clive also worked with Rhy to put on a play to help local children in need, and ended up working with a bunch of Summoned on it. It was doubtless a great success, and the children and teenagers who watched have begun to discover the concept of "fanfiction".
During the Dimming celebrations and the banquet after, she introduced herself to Lyle Vela, taking care to stress the work she's been doing to help Thorne's citizens.

And, given Jill's level of influence I'm not sure it counts but in case it does I wanted to note it: Clive will have proposed to her in public in Borrel during the Night of Many Moons.
