Red: HORSE, SPOT, MINE, DOCTOR, SOUL, ROUND, COPPER, WEB, CROSS.
Could go with “Veterinarian (2)” - DOCTOR, HORSE.
Could probably work something out with MINE and COPPER, but not sure what.
SOUL and CROSS could probably be clued with “Christianity”. That’d probably be a good start.
(gives “Christianity (2)” clue)
Blue: CONTRACT, LOG, TRACK, ROOT, DRILL, FIGURE, CONDUCTOR, CAST.
CROSS down on Red’s side. So’s SOUL.
Remaining red words: HORSE, MINE, DOCTOR, ROUND, COPPER, WEB, SPOT.
Getting into a Blue clue…
