At least with this point, there's a method to Strange's madness. If he keeps touching things and being a nuisance, then Lambert's either going to kick him out or drag him shopping himself. Either option will at least get him out of the trailer somewhat and keep him from huffing those alcohol fumes. So, as Lambert pushes him away from the table, Strange just smiles an ironic little smirk at the man.

"How long will it take you to get ready?" Strange asks, as he eyeballs one of the other beakers across the room. He's not doing anything yet, as Lambert's in the way, but he is looking at it in a suspicious manner.

And yeah, he was straight up going to put it in his mouth. And straight up does put the finger that he dipped in the beaker in his mouth, wincing slightly at the faint taste of alcohol still on his finger.
