[I2S1] HB: Manipulate the hotel's structure.
Much easier said than done. If it hasn't been made abundantly clear at this point, this place has no consistent ruleset to follow. There's no way to discern any objective truth in this malleable butterfly effect fever dream. Only way you can hope to best this smarmy ninny is by tearing the place apart to its bare foundations, taking their toys away and forcefully shoving them into a corner.
Which is a shame. You would much rather rip their potentially fuzzy head off and shout a thesaurus's worth of expletives into their bare esophagus.
Sharper is already on the major task at hand. As long as he can get over his deep seated resentment for his old flame's visage, you can take out both the structural backbone and their goons in one fell swoop.
