Here's the context:
I was once chatting with a Mexican amiga on FB and asked her if we could move to Skype instead (I often practice my Spanish with her on Skype calls). She had to say no because she was out for the weekend that moment but said we could do it on Monday.
Now here's the conversation:
Me: Mi micrófono ya no está roto...podemos hablar en Skype si quieres! Amiga: Ahora estoy en la calle y ando con mi mamá. Pero me da muchísimo gusto que ya tengas micrófono. Me: Sólo te informaba amiga. No te preocupes. :) Amiga: Pero el lunes platicamos mucho va!
The last sentence is where I am slightly confused. I get the gist of it but can't seem to wrap my head around the va at the end. What does it stand for here? I looked up the dictionary to see if ir has any idiomatic usage that fits this context but didn't find any.
P.S.: When I asked her for an explanation, she said Es como decir "lo hacemos?" but that doesn't make much sense to my simple head. Wouldn't the sentence mean the same thing without the va?
