A very confusing code problem!

I am using the following code to, visually at least, place a link marker over a complete fox hole: 
obj/FoxHole
    name = "Uncomplete Fox Hole"
    icon = 'Holes.dmi'
    icon_state = "blank"
    var/obj/FoxHole/Complete/link
    New()
        ..()
        link = src
    Complete
        density = 1
        proc/Link()
            world << "link called"
            if(usr.images["Link-Marker"] == null)
                world << "no pending link"
                usr.images["Link-Marker"] = image('Markers.dmi',src,"Link-Marker",6)
                src << usr.images["Link-Marker"]
                world << "link marker added"
                usr.link_ref = src
                src << "link_ref = [src]."
            else
                world << "pending link found"
                del usr.images["Link-Marker"]
                usr.images["Link-Marker"] = null
                world << "link marker set to null"
                src.link = usr.link_ref
                usr.link_ref = null
                src << "usr.link_ref is now null, and src.link = [src.link]."


Now, here is the problem: sometimes, the link marker pops up right on top of the hole. This is wanted. However, sometimes it appears to the side of the hole. How is this possible? Also, when the debugging message "link_ref = [src]" comes out in DS as "link_ref = Lord of Water". It seems to me that the src variable is getting messed up somewhere! Am I not correct in my understanding that src should be the hole, and not me?

I added the following debugging line to the proc:

world << "usr: [usr]. src: [src]."

And, upon running the program, it output the following:

usr: Lord of Water. src: Lord of Water.

Aah!

How/Where is Link() being called?

In response to Cinnom
The user calls it. It's added to their verbs.

If the user calls it from his own verbs list, wouldn't he be the src?

I see... then, how do I make sure that src is the hole?

Make Link() a verb, and have it set src in whatever.
obj/FoxHole/Complete/verb/Link()
    set src in world

I eventually figured it out. If I could delete this entire thread, I would. Thanks anyway, Cinnom.
