They haven't yet interacted a lot and she doesn't know too much about him, but Brennan's current impression on Glitch is very positive. He was the first person to contact her when she arrived to Taxon, kindly providing her with helpful information despite the fact that she was a bit terse with him due to the whole alien kidnapping thing. But her grumpiness didn't keep him from interacting with her again later, which speaks favorably of him! Brennan's not always that lucky, as it is. Glitch has a kind, mild manner to him that Brennan finds quite soothing and reassuring. When the full extent of the zipper thing will finally be revealed to her, it will more than likely have Brennan in a scientific tizzy of some kind, so Glitch should probably be prepared for a lot of questions about that. :/
