Liz Oki is seen performing for the panel and her blind audition hits a raw nerve with the Black Eyed Peas star.
We see in this video clip that unfortunately for Liz, no one turns for her during tomorrow night's final audition show.
But it looks like performance will have a lasting impact on Will, who tells her: “You remind me of my aunt Stephanie and thank you, thank you for singing today.”
The singer, who has lost both his aunt and grandma in the past year, adds as he begins to sob: “I had my back turned and when you said I’m so scared, I thought of my auntie Stephanie.”
And it appears that the emotion in Liz's performance comes from a recent unfortunate event in her own life.
She empathises with Will: “I think I know how you feel... I lost my mother two weeks ago.”
Watch the clip from this weekend's show above.
The Voice 2014 concludes its blind audition rounds tomorrow night (Saturday) from 7PM on BBC One.
