Does a Mage Lavellan/Inky in general, not realize you are in the fade?.. Wouldn't they like feel it or w/e?
Yeah, they don't realize it until Solas asks them "where do you think we are?".
What bugged me was that only a few hours prior I did the time travel quest with Dorian and afterwards when I talked with Solas he asked if I was sure it wasn't just the Fade and I was like " Um, I'm a mage. I think I would realize if i t was the Fade Solas!" And he approves of that answer. Now skip ahead a few hours and here I am completely oblivious to the fact I'm there.
Yea the Haven scene super bothers me... I just don't understand how she could possibly not realize they weren't actually in Haven, it was the first thought which occurred to me considering she had literally just buried Haven in a bunch of rubble 
It was definitely weird. Especially for a mage Inquisitor. I can understand dwarf Inquisitors not realizing it (not something they're used to) and I can even understand non-mage Inquisitors (since it's somewhat dreamlike) but really mages? Really?
And you could say Lavellan was blinded by love, but what about everyone else!? Trevelyan, Adaar, I thought you better than this!
