In the segment, Cross, seemingly sad and claiming that nobody even noticed that she had joined Raw, appeared to bond with Bliss, whose ring gear had been lost, and accepted to fill in for her in her upcoming match; Cross won her match later that night, a fatal four-way match against Dana Brooke, Naomi, and Natalya.[48] This was her first match on Raw since February.[49] She later unsuccessfully took part in the Money in the Bank ladder match at the Money in the Bank event, having replaced Bliss who suffered an injury.[50][51] After the event, Cross, having become Bliss' "best friend", started acting as her manager and tag team partner, starting on 19 May episode of Raw during which she, Bliss and Becky Lynch defeated Lacey Evans and the IIconics.
