Question ...
What if ... he didnt want the Dragon to see the artefact?
I mean, we still dont quite know what it is ...
And as far as i know, Red Dragons and Gith are not "allies" in the right sence of that word ... more like on "mutualy benefitial agreement" ...
So, if that Artefact (dunno if that is even possible, just guessing here) contains for example some part essence of Tiamath (or other strong Draconic thing, as i said i dont know

it might even be some shit that Vlaakith stole from Dragons, and now keeps it to maintain their "loayality") ... it would TOTALY make sence, that he leaved.
