H2o season 4

Exposed

When Coasta got back onto her boat she called up her cousin dr denmen about her research in mako and if she's seen anything weird happen. After a long conversation Coasta persuades her to tell Coasta about the mermaids she has seen. Coasta thanks her cousin and hangs up. She prepares a microscope and places Cleo's strand of hair under it, she got some DNA and was ready to go back their tonight to see who was down there in the moon pool.

Later that day
Emma and Riki had set up a gathering in the moon pool to cheer Cleo's up. Cleo swims in the pool and looks around confused as emma and Riki yells 'surprise'
'What '
We know how much you've been through so we threw you a surprise!' Emma said
'Now get up out of the water, dry off and grab some food' Riki said.
As they three girls were eating coasta went back to investigate but when she went down there she stumbles across the girls gathering and says 'were any of you girls here yesterday by any chance I found a hair sample, kinda like yours cleo.'
'No no I was at the hospital with my dad' Cleo's responds
'Okay all good hey mind if I grab a cheese ball? Coasta asks
As coasta grabs a cheese ball she knocks over the bottle of coke all over Cleo's lap.
CLEO try's to dart for the water but coaster keeps getting in her way, Cleo's pushes coaster away and dove into the pool. Coaster rushed over to try and find, cleo but what she found was something else a scale on the edge of the pool. Coasta rushes over and picks it up and places it in her pocket. She starts to wonder if Riki and Emma would act the same when in contact with liquid so she drenches them both and follows them into the pool. Coasta was amazed at what she witnessed, three scaled tails racing away, she knew their secret and realised she could make a fortune out of this scandal.
