Until he seesaw

• He would see → until he seesaw
  • A first-draft version of Finnegans wake

• s-saw: saw pronounced with a stutter, which in FW is indicative of HCE's guilt → cf. Stuttering and balbulous on this page

• seesawed: swayed back and forth → went up and down (a ladder like a bricklayer)
  • Possibly unable to balance (because drunk)?

• see, saw: to see the present and past (perhaps at the moment of death?) → cf. the future of his fates on this page

• sewsaw: go back and forth with one's opinion; a piece of playground equipment - a wooden plank resting on a fulcrum that goes up and down
