But will she be believed?
After realising that Amy has a crush on Isaac, Denise tells him that he has to stop tutoring her. Despite Isaac needing the cash, he agrees to stop.
Finding a way to see Isaac on the way to school, she watches on as Issac pockets a small bag of weed he found on the floor after telling Denise that he would hand it in on his way home from work.
With Amy refusing to go to school, Denise sees right through what she's doing and asks if it's about Isaac. And Denise and Jack are both left shocked when she says she saw him smoking weed.
When asked, Isaac can't believe it and is adamant that Amy is lying but Jack doesn’t believe him. Isaac is sure that he threw it in the bin and that she’s lying because she fancies him.
