John's ability copying &amp; Sera's (former) ability Although Sera has lost her ability and it's not clear it thats permanent or not... wouldnt Sera be the perfect foil to John? It's been shown that John can't seem to copy time based abilities (such as the green haired girl on the stairs at Wellston, I forget). If Sera got her ability back, I don't think John could mimic it like other abilities.
