her power sounds perfect! all of the siblings seem to have powers that aren't elemental, which works really well. i think marlee would've been more than happy to travel with her and try to help her out. her own ability of power replication showed up when she was an infant so i imagine she would try her best to help her siblings if she could. and since they were travelling together for a while, if they touched at all, marlee would copy her power for a bit. i'd love for them to be close!
