If you want to move Frost to you instead of moving you to him, you can use the following commands in the console:
Prid 00097E1F
moveto player
Prid
selects an object by form ID and moveto player
moves the selected object to the player.
A comment on another answer mentioned the possibility of using player.placeatme 00097E1F
. That may work for this particular quest (I haven't tried,) but, just as a head's up, that will create a new instance of the NPC instead of moving the existing one to you. The Prid/moveto command combination listed above will move the existing one to you. I'm not sure whether it makes a difference in this case, but it can in other cases (for example, if Serana goes running off in the Soul Cairn.)
