The second season of Seven Deadly Sins is really not even a season at all. It is 4 episodes of mostly filler. That being said it does not make it any less enjoyable. Many have complained about personality changes however this is not true, everything is developmental. Diane changes as she regains her lost memories. Gil is a lot more laid back and less serious now that Margret is safe. Jericho's opinion of Ban changes due to the fact he saved her brother and herself from the Demon. At the end of the day Season 2 is probably best called an OVA but it is stilla good watch
