Both Irene and Hugh love the "beginning place", the threshold; they feel a sense of belonging and home there that they lack elsewhere in their lives.
Despite her anger with Hugh, and her resentment of his disturbance of her hidden sanctuary, they find that they must work together; she has had increasing trouble in passing through the gateway into the other place, while he cannot always cross back into the 'real' world.
Hugh is welcomed in the town as the hero for whom they have waited; Irene is jealous, wanting desperately to win the admiration and respect of the townsfolk and especially the Mayor or Master, Sark, whom she has loved for a long time.
Hugh is largely unaware of her feelings, but wants to complete the quest to become worthy of the Lord of the Manor's daughter Allia.
On the other side, the trust and the love they have discovered together opens a different sort of gateway, providing them with a possible future together that avoids the destructive patterns of their own families.
