Prediction: Sparkpaw takes after her mother and is gonna be the rebellious kid who takes orders from no one!! Especially not from Bramblestar aka her dad!! because she wants to shake off the fact that she looks exactly like Firestar and is afraid she cant live up to everyones expectations 

Alderpaw, however, is actually gonna be our new “Firepaw”, wanting to help everyone, natural leader, Thunderclans little prince. He’s just naturally kind and good at whatever he does. Since he wants to be a med cat he’s gonna have to deal with grumpy Jayfeather as his mentor. Jayfeather cant stand his saint like behavior (yet still loves him like any older brother would) which means that the two of them argue like all the time.
