-5:40 he goes into woods towards ezalor who is IN FOG charging his 1st spell towards sylla and at 5:54 just look at the hook into the fog. That can't be skill. He waited neutrals to get out of the way and then hooked, and he couldn't see that without mh, they were in fog.
-6:15 and 7:00 These two hooks are a little suspicious, but it could be just skill which I highly doubt based on what I've seen in the whole replay.
-12:32 This one is suspicious too.
-16:30 And this one is very very suspicious.
That's all, if I didn't get dc'd in mid game I'd probably provide more evidence, but I think this is enough, especially the 5:40-5:54 case. There were no fog clicks unfortunately.
