Germany packed sunscreen for Prussia, so he DOESN'T NEED YOUR SUNSCREEN SPAIN.

But yes, Spain can tease Prussia. And Prussia will definitely start to act competitively with Spain when any games pop up (German soccer > Spanish soccer), but yes, in the end Prussia will still work together with Spain. There are some things that just cause people to bond together, and beating up Austria just happened to be one of them.
