Yes, but the chains could just be another red herring, sort of like the Gumillia-Nemesis situation. Also, in the Evils Kingdom album cover, we see an unknown Len character reflected in the mirror facing Allen. "Rin" is reflected in the mirror facing Riliane, so if it follows the pattern, that means the Len character is someone Allen becomes. Allen and Irregular are seen in the same place at the same time, thus confirming they're separate beings; the only way for Allen to become Irregular is by way of time travel, which is a bit unlikely.
