Oh Alright Then

It's another type of way to say 'exactly' when used In a situation where somebody claims something that has no proof and you question them but they say silent because they have nothing else to say.

Lia: You stole my pencil!
Gina: How? and it has my name on it and your pencil is on your desk?
Lia: ..............
Gina: Oh alright then (exactly)
