Personal I believe that what Wanda did was the gamechanger. Before she created the 'Waiting Room'
the ressurection protocols didn't realy ressurect mutants but rather created clones/copies, new entities, of the original. Nowhere in the descriptions I found about the RP was mention of a soul being retrieved and placed in the new body. Now with the 'Waiting Room' this is different. The 'Waiting Room' collects the souls before they travel on to the afterlife and allow them to be placed in a new body as part of the ressurection proces. Making Thunderbird one of the first 'truely' ressurected mutants.
However, when considering this I do have a few questions :
- Before the 'Waiting Room' there have been several mutants who died and have been through the RP several times. Are there now multiple slightly different souls of the same mutant in the afterlife ?
- Are the souls of those currently ressurected the original souls or the most recent soul of the mutant that died ?
- If Moira X was to die with her power intact would her soul now be 'captured' by the 'Waiting Room', thus preventing a reset and allowing Moira to be ressurrected ?
This whole RP mess and the loss of the 'originals' might be a reason why a Moira-reset of this timeline might be desirable
(and create a new Krakoa-timeline with a 'Waiting Room' as part of the RP from the start).
