Upwelling
The major upwellings in the ocean are associated with the divergence of currents that bring deeper, colder, nutrient rich waters to the surface. There are at least five types of upwelling: coastal upwelling, large-scale wind-driven upwelling in the ocean interior, upwelling associated with eddies, topographically-associated upwelling, and broad-diffusive upwelling in the ocean interior.

During her time in the show, it was hinted that Eddi liked to drink. Potts pointed out that drinking did appear to be the only way Eddi could deal with her many issues. Potts hoped the storyline would explored further, especially as Eddi's mother was an alcoholic. She also thought it would be fun to see Eddi lose her grip. Potts added that studies had shown people with alcoholics in their families became predisposed to it themselves.
In March 2012, Eddi's younger brother, Liam (Luke Tittensor), was introduced. Eddi was "spooked" when a female patient revealed personal details about her, but she then saw the patient kissing Liam. Eddi was not comfortable with Liam's arrival and it was revealed that Eddi ran away from home to escape their alcoholic mother, leaving Liam to pick up the pieces. Knowing that Liam had been in trouble with the police, Eddi worried that he had run away. She then decided to fix things with her brother by calling his youth rehabilitation scheme to organise his transfer to Holby. A spokesperson told "Inside Soap's" Katy Moon that Eddi may have bitten off more than she can chew.
