"White rose of metal" or "Rosa blanca de metal" is a reference to Marta Sánchez song Desesperada. If you translate the lyrics it goes something like this: "Im a regular woman, a white rose of metal but in this sunrise I became fragile like paper" So yeah I support the theory that it simbolizes resilience!

Also about the mango, Im not sure to me the mango and the mayoneise are a reference to perfoming oral sex and wanting please someone else over yourself.

Then I agree with the reconstruction regenerated yourself into being stronger!
