the other times was a little surprise but more like oh hey! you're here but that one you are likely sprinting through the basement hoping there's not new molded and that room in particular had the most so just running smack into something in the room can be startling as you're half expecting molded haha
A fun topic might be what's the weirdest place you've seen her? Then again, maybe not because she has a static set of places but we might learn of ones we aren't familiar with this way. For instance, I challenged my friends to find her in a weirder place then one I saw which was in that little crawl space you use at the beginning of the main house to get into the laundry room for the first time. It was my first play session and I was about to head into Lucas' area and being the last area you could reach from the back yard, I decided to make sure I hadn't missed any coins before proceeding as I'd be trying to find them on my own. Turns out I was missing one coin but looking through a coin guide, I could swear I'd already picked up all of them. So I had to double check every one...eventually that led me to checking the one that's on the lawnmower in that tunnel. I drop down the hatch door and bee-line straight for the lawnmower, really focused and trying to speed run this. It's not there...but as I turn my camera BOOM old granny is in touching distance! How the hell did I miss her? How the hell did she get down here? Her head is touching the grey pipe above us lol At this point in the game I wonder how the hell she could get there. Upstairs? Jack could carry her, maybe there's a secret elevator I don't know about but this tiny ass tunnel? No way a wheel chair would get down there! Surprised me to say the least.
As for the coin, ended up being the one in the guest house, the only one that was completely miss able at that point

Then I'm further trolled by going back there at the end. I was so excited thinking I'd get the chievo after all! Only for the drawer to refuse to open

You can't even read the newspaper sitting on the kitchen table at that point in the game. The bummer was that I actually did the harder part, found the lockpick in the video and picked the drawer but in light of Mia attacks, I spaced going to the drawer with Ethan. Doh!
