Is anyone else bothered by how sneaky sneaky Vhagar is?

SPOILERS FOR EPISODE 4

I love the show, but sometimes we get a Rhaenys killing small folks, or a Rhaenyra sneaking into Kings Landing. The latest thing to irk me a little in episode 4 has been how sneaky Vhagar has become.

Cole has been on a march for days with Aemond chilling at Kings Landing. Vhagar is supposed to be their to safeguard the place. How is Aemond able to get that behemoth out into a forest without anyone noticing? Especially when the blacks were shown to be so vigilant that they saw a few knights on horses that too far away from Dragonstone.

Followed by this was how Vhagar after his fall, disappears again, and is seen emerging from behind the castle to bite down on Maleys.

Vhagar's sneaky sneaky in the clouds was horrifying because it seemed possible. Lucerys death made me gut churn because that seemed possible. But the one with Maleys? Meh. I think that was a death for a deaths sake.

I loved all the harrenhall stuff. The small council scenes were tense. The passing down of the dream, "A song of Ice and Fire", was hype!
