Pete's a sly dog
In the episode Lost & Found, Pete introduces Reed to Kathy, a woman who works at a teen hotline at Rampart Hospital (yes, that Rampart). Pete & Kathy have obviously seen quite a bit of each other.
But... in the very first scene of the episode, Reed makes mention of a double-date the two guys are going to have that evening, and he says something about Malloy wanting to make a "good first impression," so it's obviously a first date. That means that sly-dog Malloy (or should I call him the Strawberry Fox?) is dating two women at once. 👊
