looks like a buildup for a war in this arc. Early, we were shown many giants are not into war and want to live in peace and study. Now they are being conquered by WG.
Probably, fake shanks is calling his dad to complain about loki not joining and summon his friends to attack elbaf. This will turn many giants to fight against WG by allying with SHs. Loki will also form alliance with them and after this arc will probably leave elbaf, leaving hajrudin to be new king of elbaf
