The CJ twins meet Splinter (but the catch is Casey is absolutely terrified of rats)
They're all pretty close by now (especially April and the jones kids) but Splinter really dislikes having others enter his home (and especially other humans, considering he used to be human too)
April doesn't usually listen but Splinter is used to that (he has 4 kids that are always so rowdy)
April also didn't know Casey was terrified of rats and right after this she profusely apologized to him and Cassie.
