I am not sure why Marvel likes putting blood splatters in the oddest of places these days. It must be when they wanted to become more family friendly or is it when they wanted everyone else to be more that way. Either way it looks odd.
The Fox Pietro is definitely more like Evo Pietro with the way he is dressed and his personality but 616 Pietro played the Moonlight Sonata on the piano once and I can't see him wearing a Nirvana t-shirt.
