The last time that Thor had attempted to use Mjolnir to deflect a shot from Gungnir, the resultant blast had sent him through the metal brick walls of the Healing Rooms. So this time, Thor attempted to dodge, instead of blocking. Yet speed and agility were difficult, with both no warning, and with Thor's large, muscular mass. So he took the hit to the shoulder, and it threw him back into the boulders behind him.

"Loki, there is no need for this!" he shouted, reluctantly drawing Mjolnir.
