I think she will
Most suitable candidate
Also, I can guarantee that what was written in Oden's journal is some vague info, she will not be a walking spoiler on the ship
Her strength is a plus
Lastly, her role will depend on what skillset/interest she has, so we'll have to wait
I don't think she'll be the lookout cause I believe that position is reserved for someone else, also it doesn't suit the likes of her attitude which I'm assuming resembles Oden
If I had to guess, she might play the "scout/ messenger/representative" roles
Meaning, once we reach an island, she just jumps on the island scouting (just like Oden used to go ahead not listening to the crew Lol)
Would be so Oda if he made a gag about it, that she's a scout that always gets entrapped like Zoro losing direction...etc! Specially like what we saw from Oden
She can be the messenger/representative also when Luffy for example sends someone to talk to the other crew boss (like Rockstarr and WB)
But that's good because, her looks is fine and beauty, so she isn't hostile while negotiating, also, she's strong and can defend herself until back up arrives
I used to think Jinbe would take that role considering how he knows how to negotiate, but since he'll be controlling the helms in case any bad thing happening, someone else, LESS reckless than Zoro or Luffy, and less of a simp than Sanji, and STILL strong to hold his/her own if got attacked
She is perfect For that role
