Towards the end of Thor: Ragnarok, when Hulk is fighting
we see his (Hulk's) leg pierced
by Fenris' fang,
and some blood seeping out into the water.
A) Is this the first time in the MCU that the Hulk has bled or had his skin pierced. (IIRC Banner cut his finger in the first Hulk film, but that's not the Hulk)
B) Was there any significance to the bite, or the bleeding - it seemed like the camera lingered on the shot a little longer that I would have expected?
