Penta already is almost done with his injury time so he's out either way, it's just Fenix that would be awhile. The timeline actually makes a lot of sense now since it was revealed Penta had like 2 months added.
While I do think he fucked it for them, I hope WWE doesn't really hold it against Penta still. Hopefully they just laugh it off and still give him something solo and not just wait for Rey. Don't want him slumming it in Mexico for 9 months. And likewise, Rey better not be sitting at home the whole time either
