You're in the audience at Jimmy Kimmel while talking to Sebastian about the metal arm and how he wore it.

“What do you mean it has lube?” Jimmy asks.

“Well, I gotta in there,” Sebastian says, looking you straight in the eyes and grinning mischievously.

The two of you had a one night stand after the shoot and you expected him not to remember you, but he knows who you are. You blush as you realize he meant that comment ambiguously. He didn't just need lube for his arm.
