Drake: You saw Heimdall wound Loki, what you're not seeing is that wound regenerating. Next time this group faces Loki, and there will be another time try and attacking him, you will find it futile.
Really the only one Loki has any fear of is Heimdall, but that is because of Heimdall's eyesight and hearing.

As Odin says in the Hovamal:
"Praise no day 'til evening; no wife 'til on her pyre; no sword 'til tested;
no maid 'til bedded; no ice 'til crossed;
no ale 'til drunk."
