When your friends were down, you rallied around them for comfort and support. Clark would have moved heaven and earth if need be, just to make sure that he could keep Bruce company and possibly cheer him up. He'd never brought it up, but sometimes, he worried that if he wasn't around as much as he was, Bruce would slip into a depression, and retreated even more into his shadowy world. That was part of the reason Clark was grateful for Selina's presence.
Kryptonian ale was a surprising find amongst the archives of the Fortress of Solitude. He'd never really expected his father to include recipes for things, especially alcohol. But he'd mixed a batch and given it to Bruce to sample after the first brewing. Bruce had remarked that it was strong enough to fuel the Batmobile. Even Clark could feel the effects of it after a few sips.
He returned with the ale and a few pies as promised. Ma had scolded him about the short notice, but somehow, had found a few down in the cellar to bring. And of course, there was the standard strawberry rhubarb for Bruce, as it was his favorite.
Arriving before Tony, Clark wandered over to Bruce's side. "I thought that me bringing pies to social functions annoyed you," he said with a grin, setting the tray down along with the bottles. "You looked like you might have a stroke the last time I did."
