Garry gatecrashes Britt and Siôn's party

Britt and Siôn's party is a success, until Garry gatecrashes and realises where Sioned got the money to pay for her new dress.

Meanwhile, Gemma is caught up in Andy and Angela's web of lies. She doesn't know who to trust.

Mae parti Britt a Siôn yn llwyddiant, tan i Garry sylweddoli arian pwy wnaeth dalu am ffrog Sioned.

Caiff Gemma ei dal yng nghanol celwydd Andy ac Angela. Dyw hi ddim yn gwybod pwy i gredu ac all hi ddim gofyn i'r un person mae hi'n ymddiried ynddo.
