[Walter does get a bit of an offended stare when he starts laughing, but that dies down into a shocked one when he explains the reason why he's tickled pink.]

No w-way...so you're dead too? Shit man...I'm sorry to hear that. How'd you-

[He catches himself right there and swallows hard.]

...sorry. I shouldn't ask.

[The nervousness dissolves into an awkward grin right back at Walter. He doesn't even realise he's mirroring Walter's movement when he rubs the back of his own neck and chuckles dryly.]

Kinda fuckin' weird if you ask me but...yeah, guess we do. Never thought I'd say it though.
