I was replaying Half Life 2 the other day and I was thinking to myself while disemboweling zombies with the buzz saw gravity gun combo;" Why did Alyx tell me to go this way"? Seriously it isn't as if you are trapped and the only way out was going through Ravenholm. If that were the case wouldn't Dog have gone with you. I know it wasn't to keep you safe so why did Alyx tell you to go that way? Was the reason just so we can see Father "Batman" Grigori?
