Pupsicle

Pupsicle is the HET ship between Marrow Amin and Winter Schnee from the RWBY fandom.

Canon
Before Winter was promoted to leader of the Ace-Ops, there wasn't much interaction between her and Marrow.

After Winter was promoted however, Marrow was willing to follow her orders at first. During the Battle of Atlas, their relationship was seemingly strained when Marrow asked If Winter was really willing to bomb her sister's friends. While Winter initially responded with a cold "yes", she decided to turn around and address Marrow with more warmth to show him that she wasn't thinking like Ironwood. Because of this, Marrow's eventual betrayal against the military was delayed due to this kindness.

Winter and Marrow later began to share the same vision and thoughts of Ironwood. When Marrow finally couldn't take Ironwood's orders anymore, Winter quickly realized Ironwood would have killed Marrow on the spot and intervened, making a show of arresting Marrow as a traitor and claiming she would put him in lock-up. When they were alone in an elevator, she undid his restraints and confirmed their mutual thoughts that Ironwood had to be stopped although they briefly bickered as Marrow complained about Winter hitting him, which she explained was to fool Ironwood and to save his life. They met up with Qrow and Robyn and contacted Weiss in order to plan out a means to save everyone and stop Ironwood.
