@Roadrunner9000 maybe he expected to get noticed either way, and figured it was better to get some noble ally even if he painted a target at his back earlier than needed. Though, if he doesn't clean up the guy he sowed a grudge with before next day, then I can't think of any reason at all (what use is an ally, if to get one you had to get a more powerful enemy?).
But no, I agree. It feels forced, OOC, and like the girl is only there for her (non-existent) boobs.
@CookieLoop Nope. I am just thinking of a covert operative who has the choice between getting in trouble and not getting in trouble.
And how said trouble is likely to find him either way, eventually, minus the actual grudge (and that he is fully capable of subtracting said grudge himself, in the span of a single night).
