Is an object still connected to a list after FirstOrDefault?

ienumerable

Here's my code:

        Event thisEvent = (from i in list
                           where (i.eventID == eventID)
                           select i).FirstOrDefault();
        if (thisEvent != null)
        {
            thisEvent.eventResolved = resolved;
            thisEvent.eventSequence.Add(item);
        }

"list" is a collection of IEnumerable, i.e.

IEnumerable<Event> list;

What I'm wondering is: after creating thisEvent using FirstOrDefault, is thisEvent still connected to list? In other words, when I change the two properties, eventResolved and eventSequence, is "list" actually changed, or is thisEvent just some totally disconnected copy of an item in "list"?
