While Newton was in the hospital in a coma, the first three pages of "Infinity Inc." #12 were sent to Thomas. Rubinstein was brought in to ink them and Newton’s Phoenix friend John Clark lettered the pages at Thomas' request. As a final tribute to Newton, Marvel Editor-in-Chief Jim Shooter let Rubinstein out of his contract for a month so that he could ink a fill-in issue Newton had done. It became "Infinity Inc." #13 (April 1985). This was Newton's last published original work.
