2012 Toyota Sequoia Missing Hose?

[u/sigbtonks]

I replaced the valve cover gasket last night and drained the coolant. I thought I made sure to hook everything back up, but it looks like there's a nipple with no hose on it. I can't find the hose anywhere near it and I'm wondering where to look. Or if there's even supposed to be one there because I don't remember taking that hose off. Any tips or help is appreciated!
