Faith made her debut on EastEnders last week and fans are about to see her transfer over to internet spinoff E20, which follows the challenges she faces after Grace (Ellen Thomas) has kicked her out.
Adeyeye told Digital Spy of her alter ego's E20 journey: "Faith's main storyline is that she wants to get back to Grace's house - she really wishes she could get back there. She soon realises that she wants to be living with someone who she loves, and someone who loves her too.
"Faith is a girl who really craves love, but she just doesn't know how to go about it. As Faith's journey goes on, things get a lot harder for her and she realises that she needs her grandma."
EastEnders: E20 sees Faith meet up with troubled runaways Ava (Sophie Colquhoun) and Donnie (Samuell Benta) and they soon hide out together on Albert Square. However, Faith is the only one of the trio who appears in the main soap.
Discussing the experience of appearing in both shows, Adeyeye said: "I think it was a good opportunity as Faith is in EastEnders and it leads into E20, so it builds up the buzz for what's going to happen in E20.
"I think it was a really smart thing to do, as the viewers are going on a journey with the story and it takes them into E20. So even though Faith then comes out of EastEnders, she goes into E20 and you see a lot more of what happens - the grittier side."
EastEnders: E20 launches its third series at 8pm tonight on the official BBC website.
