Relationships
Allison

Holston and Allison appeared to have a loving relationship; Juliette noting that when she met Holston, he talked a lot about his wife.

Three years prior to the start of Wool, Holston and Allison won the 'lottery' - a system in place that, when won, allows a couple a year to try for a child. During this period, they resorted to superstitions to aid them, including hanging garlic over the bed to increase fertility, putting dimes under the mattress for twins, pink ribbon and blue dye. However, their year was cut short when Allison was sent to cleaning.

After her cleaning, Holston held out the hope that Allison would return for him before ultimately deciding to go out after her as he believed without Allison he had nothing to live for.
