Sean Reynolds first arrived in Emmerdale on 10 March 1999 along with his wife Angie, and two children Marc and Ollie. Sean settled down with his family in Emmerdale, and set up his own haulage firm. However, he found himself in stiff competition with rival businessman Chris Tate, who, like Sean, owned a successful haulage firm. Sean's stubbornness not to let Chris gain the upper-hand often got in the way of his own business, and there were several confrontations between Sean and Chris. At one point, Angie suggested that Sean become business partners with Chris, but Sean abruptly brushed this idea off. Sean's establishment as an unattentive husband and unfit father made him notorious in Emmerdale as a potential misery, and he became very unpopular with his fellow residents.
