Prosecutor Edward Brown KC said: "You will see that Cher Maximen had been knocked to the ground in the immediate events as Adjei Isaac recoiled from Shakeil Thibou’s knife.
The Old Bailey heard Shakeil Thibou, 20, had attempted to stab Adjei Isaac when he instead knifed the mum in the groin.
The court heard after she was knocked over, Cher attempted to pull herself up using Shakeil Thibou’s coat.
Meanwhile, Shakeil Thibou thrust a "huge" knife repeatedly towards Adjei's stomach - only missing him because the victim moved back.
She then attempted to "strike out" at Shakeil, who allegedly raised the zombie knife and "deliberately thrust it towards her, stabbing her in the groin".
