A new sneak peak has been released for this week’s episode of The Big Bang Theory, previewing an unexpectedly sweet interaction between two very different characters. Minor spoilers ahead.

A new preview clip from “The Monster Isolation”, tomorrow night’s episode of The Big Bang Theory, has been released online. Though the episode promises to bring the romantic drama for at least one member of the geeky gang, it looks like another unexpected pair will enjoy the outcome of a very different kind of performance. Check out the clip right here:

It’s hard not to feel sort of “Soft Kitty” inside when Sheldon responds like a normal human friend, and it’s great to see him express gratitude for Penny’s help. We also can’t wait to watch Penny make her debut on “Fun With Flags”, and – no matter what Sheldon thinks – get a glimpse of Penny in her new play. Check out these stills for hints at these scenes and other peaks at the episode.

The official summary for “The Monster Isolation” focuses on woes which are not hinted at in the sneak peak clip – namely, Raj and his most recent romantic misfortune.

After a terrible date, Koothrappali vows to never leave his apartment. Meanwhile, Penny actually impresses Sheldon with her acting skills.

The Big Bang Theory will be on hiatus next week, but will return with “The Contractual Obligation Implementation” on March 7. CBS says:

Leonard, Sheldon and Wolowitz speak to junior high girls about careers in science. Meanwhile, Koothrappali plans a date with Lucy.

Do you predict permanent isolation in Raj’s future?
