Never
one to give up on a guy quietly, Theresa heads over to the Loveday flat
to seek answers - but she can't believe her eyes when she finds Zack in
bed with someone surprising.
Zack is left humiliated after being caught in
the act and desperately tries to make things up with Theresa, but she
turns vengeful by threatening to tell the whole village what he's been
up to.
Later, Theresa renews her bond with Fake Lisa and realises just how much the impostor is in love with Zack.
When
Zack later kisses Lisa and makes his feelings clear, does this mark the
beginning of a full-blown fling for the false siblings?
