Yeah it was really just to show Minerva's power but I just remembered after the battle with Bickslow Lucy begins resting so that just made me think about the whole Loke using up her magic and I would say being attacked like that would mess with a characters ability to use magic, but maybe the clash between Juvia and Aquarius cost more magic then we thought. Anyway I think I now know why Loke didn't come out. You see Loke is Leo the Lion and a Lion is a Cat and what do cats hate? Water! Cats hate water so Loke didn't come out because like a cat he hates water and before you "but in the against Angel he was standing in water" well I’ve seem cats walk through puddles and the level of water only really covered his feet like if a cat walked through a puddle. So there Loke didn't come to help out because he can't stand deep water.
