The actress, who has been on screen as Kylie for nearly a year, hinted that viewers can expect her alter ego to feature in lighter storylines with the Weatherfield newcomer.
Eva, played by former Emmerdale and Lilies actress Catherine Tyldesley, moved into the Rovers Return last month after her mum Stella took over as the pub's bar manager.
Speaking of future plotlines, Lane told Inside Soap: "We're going to see a happier side to Kylie as Eva becomes her sidekick.
"Catherine and I are a bit of a nightmare together on set, too. We laugh a lot and mimic what the other says!"
Lane also admitted that she is keen for Kylie to get on good terms with half-sister Becky McDonald (Katherine Kelly) before the troubled blonde leaves the cobbles in early 2012.
"I've got a bad feeling that Becky is on a downward spiral, but I'm rooting for her and Kylie to finally be able to work out their differences," she said.
